Cumulative Sum (convert Into Terms Is SIGMA)
Dec 31, 2008
I have, for my formula, 2 constant values a and x, I then also have a variable, n. The formula I'm trying to convert into excel terms is
SIGMA (with respect from 1 upto n) ((1-x)^(1-n) * x)*a. Unfortunatly thats not drastically inteligable so i've attached a picture file that should explain it in more understandable terms. Now the problem im having is, sigma is a cummulative funtion, which in this example is relative to the variable n, firstly I don't know what formulas I would have to use in order to get a sigma/summination function, and secondly I am uncertain of how to link it to a variable range.

I have this equation that i am trying to run in excel as a formula but how to write the correct function:
fk=E(1/i)pk(i)
where E is sigma with the lower limit of the summation equal to 1 and the upper limit being variable (depending on the sample)
i have calculated all the individual terms, i just need to know how to run the sigma function in excel.

I want to find the correct formula to find answers using excel for the folliowing:
1. >3Sds
2. 3SDs<>2SDs
3. 2SDs<>1SD
4. <1SDs
This question uses 3 sigma rule (see attached worksheet) and the formula needs to be re-arranged to meet new criteria. So, we need to consider both sides of nornmal distributiion (ND) curve. eg. when we say >3SD it means it should count all valuee falling in the rage "Mean(Average)+3SD AND Mean-3SD" i.e two extreme ends of the ND cureve. I have inserted a normal distribution diagram and colour coded the ranges so that it will be easy to identify. Please refer comments inserted in K7to N7, cells that contain formula that need to be reset.

Is it possible to enhance this line of code:
Code:
.Range("A1:EH" & llastrow).AutoFilter Field:=10, Criteria1:="Cows"
Which filters my database to display only rows in which column J (10) equals "Cows", to display all rows that equal "Cow" and "Chicken" and "Giraffe" and "Cheetah"?

I'm writing a macro to search for letters A to Z in one spreadsheet, and copy it's associated data into another spreadsheet where A to Z already exist.
Thus:
Cells.Find(What:="A", After:=ActiveCell, LookIn:=xlFormulas, _
LookAt:=xlPart, SearchOrder:=xlByRows, SearchDirection:=xlNext, _
MatchCase:=False, SearchFormat:=False).Activate
That works fine. It find's "A", then the rest of the macro moves to the right and copies the data needed:
ActiveCell.Offset(0, 1).Range("A1").Select
Range(Selection, Selection.End(xlToRight)).Select
Selection.Copy
THEN it goes to the NEW spreadsheet (where A to Z are already labeled) and pastes into the corresponding area. Thus:
Windows("The Other Sheet.xls").Activate
Cells.Find(What:="A", After:=ActiveCell, LookIn:=xlFormulas, _
LookAt:=xlPart, SearchOrder:=xlByRows, SearchDirection:=xlNext, _
MatchCase:=False, SearchFormat:=False).Activate
ActiveCell.Offset(0, 1).Range("A1").Select
Selection.PasteSpecial Paste:=xlPasteValues, Operation:=xlNone, SkipBlanks _
:=False, Transpose:=False
This works perfectly.
However:
What if, one day, "A" does not exist in the source data? If say, the data started at "B", because there were no results for "A". Currently, the macro will stop working if it attempts to search for a value that doesnt exist.
How do I make it, for example, Search for "A", find that "A" doesnt exist, then skip to Searching for "B", and then "C" and so on?

I have created a dictionary with technical terminology. It is in excel format with about 10,000 entries. The format of my dictionary ("Sheet1") is in three columns:
<vocabulary term> <pronunciation> <definition>
Now, I want to create vocabulary lists using my dictionary. The newly typed up vocabulary list (which only has the term, but not pronunciation or definition), will be copy and pasted into "Sheet2".
The "Sheet2" typed up vocabulary list is in the format:
<vocabulary term 1>
<vocabulary term 2>
etc...
I want to run a macro or script to dictionary terms (including pronunciation and definition) from "Sheet1" and put them into my vocabulary list "Sheet2".
The desired output list in "Sheet2" is: .....

I would like to create a code that would summarize any day of the year in numerical terms.
The formula for coding "days" is as follows:
Coding Month value + current day
Where "coding month" was a combination of the year and month.
The year can be summarized as a fixed value:
2007 yr = 4
2008 = 5
2009 = 6
Ignore anything prior to 2007 and anything after 2009.
The month is simply a SINGLE digit to represent the month and where
January=1, feb=2, march=3......Sept=9. Once you hit October, you have to reduce the values to a single digit, so October = 10 = 1+0=1, November =11=1+1 =2, December = 12 = 1+2=3
Therefore, May 2007 = 4 ( 2007 ) + 5 = 9
June 2007 = 4 + 6 = 10 = 1+0 = 1
Now, comes the addition of the individual day to the mix. If you wanted to find the value for May 23, 2007
You know that May 2007 is 5+4 = 9 so adding the 23rd day is 2+3=5
therefore 9 + 5 = 14. Right?
Not really...
Before reducing this final number down further, there are some double digit numbers that DO NOT get reduced further. They are:
a. 13,14,16,19
b. 11,22,33,44,55,66,77,88,99
These numbers have to be left as is. So, today, May 23, 2007 would be left as a "14"
Two more examples:
May 24, 2007 = 5+4+ 24 = 5+4+2+4 = 15 = 6
July 17, 2007 = 7 + 4 + 17 = 7+4+1+7 = 19 = left as 19
Final thought - It would be helpful, though not necessary, to have a notation besides these double digits. If series "a" could have a "KD" next to it and series "b" could have a "MN" next to it,

I have thousands of data entries (each in their own row, all in one column) and need to separate the basic info. In the example below, say you want to isolate the Town names by entering a formula that can produce a TRUE or FALSE result. Is there a way to use the FIND function and a pool of terms to isolate cells that contain excess data (i.e.- produce a FALSE result for cells containing any words from a term pool like : "Police, Park, Power, Water, Community, Bakery, Grocery, Field, Garden, Post Office, School" etc... ) ?
Pic of sample spreadsheet with desired result:

A3 = Springfield Police Department
A4 = Springfield Community College
A5 = Springfield Park Of Recreation
A6 = Des Moines
A7 = Des Moines Power & Water Company
A8 = Des Moines Sunrise Bakery
A9 = Des Moines Post Office
A10 = Des Moines Grocery Store
A11 = Lancaster
A12 = Lancaster Baseball Field

I have the formula where i can change a date to its equivalent in terms of quarters system with a date:
=CHOOSE(MATCH(MONTH(A2),{1,4,7,10}),"Winter","Spring","Summer","Fall")&YEAR(A2)
This is a school year configuration.
ex.
A2 = 10/1/2005: with the formula up there it turns into Fall 2005
i want to be able to add any number of years and the formula will still come up with the quarters system
also i would like A2 to be stationary and create a list of quarters for each year i add on
ex.
A2= 10/1/2005 B2=Fall 2005
B3=Winter 2006
B3=Spring 2006
B5=Summer 2006
B6=Fall 2006
etc.
If this is all possible lastly I would like to negate summer quarters

1) This exercise would save me considerable time and would almost certainly eliminate the possibility of typing errors in preparing the input data file for another application.
2) My program requires each input multivariant equation to be specified as follows and in the same order:
--Number of Independent Variables, N (max 10)
--Number or Terms, M (max 20)
--Term 1: power of var 1
: power of var 2
: ..............
: power of var N
: coeff
--Term 2: power of var 1
: power of var 2
: ..............
: power of var N
: coeff
........................
--Term M: power of var 1
: power of var 2
: ..............
: power of var N
: coeff
3) It would be extremely helpful if I could type the equation (of up to 10 variables and up to 20 terms) in a cell on a w/s and automatically get the above particulars extracted and nicely tabulated in a column.
4) Simplified Example: (3 var & 4 terms).........................

I need a cell that holds a cumulative sum , but i get stuck into cell self reference.
Let me explain . Imagine i have cell A1 which holds a formula : =B1 + C1
If i keep changing the values of B1 and C1 the value in A1 will be changing as well . I need to the sum up of A1 values at any given moment. I practically want
A1 := A1 + B1 + C1

I would like to work out the cumalative value ffor each row on a sheet I have.
Basically it just needs to start from column 4 each time and then go across and take first value and then add that to the second one, take that answer and add to third one and so on. Basiaclly I need to get an end result on clolumn 25 each time. The code has to be able to count down the rows too.

This problem has come at the end of a big exercise whereby I've managed to construct a spreadsheet that automates three payment processes based on various VLookups to another file. However, I've come to a stage where I need to pre-empt a payment allocation based on cumulative totals.
I'll try and explain clearly below but I've also attached a spreadsheet showing the intended result (along with a copy without the output so that someone can add in the formula - again, if it exists.
So, this all centres around a code allocated to our clients and a declaration that they complete. Say client code "Apple1" (col E) sends in instructions to pay on a position of "650,000" (col F). Within our existing spreadsheet we have an available position of "800,000" which can be seen by totalling column G for client code "Apple 1".
So that's the first requirement - for all rows on my existing spreadsheet for client code "Apple1", I want to add the cumulative total of column G ("800,000") I'd like this captured in column H, as per my example.
We can then make payment based on their declaration, up to their total available amount. However, we need to pay them in stages according to our existing allocations (col G). Therefore, taking the first example, their declaration show's an available position of 650,000, their total position is 800,000 and the available nominal amount for that row (col G) is 200,000 - so they can be paid on that full amount therefore, 200,000 should be shown in cell I3.
So now, they've got 450,000 left to be paid and cell G4 again shows a position of 200,000, so once again, cell I4 should show 200,000.
The client "Apple1" now has a payment amount remaining of 250,000 remaining but in this instance, cell G5 is for 300,000 - so because the remainder of their available payment is less than the amount in cell G5, we should post the available payment amount in that field - 250000.
Therefore, if you add up all of column I for client "Apple1" it comes to 650,000 - the amount we have on our declaration - even though the total of their available position is 800,000.
I've included another client in the mix "Sauce2" who should show 200,000 and 0 respectively in cells I6 and I7.

Is it possible to arrive at the formula result in cell (C9) using only the cells in column A and bypassing the need to have a column B?
I originally tried =MIN(A1:A9)-MAX(A1:A9) as a way to bypass column B and have a single formula but it did not give me the same result. I was thinkging I might need to have a (UDF) but not sure. Thanks Again.
Column A ------------------------Column B-------------------------Column C
A1=2.53 ------------------B1=A1-Max(A$1:A1)
A2=3.52 ------------------B2=A2-Max(A$1:A2)
A3=5.47 ------------------B3=A3-Max(A$1:A3)
A4=6.87 ------------------B4=A4-Max(A$1:A4)
A5=7.89 ------------------B5=A5-Max(A$1:A5)
A6=4.14 ------------------B6=A6-Max(A$1:A6)
A7=3.23 ------------------B7=A7-Max(A$1:A7)
A8=2.10 ------------------B8=A8-Max(A$1:A8)
A9=12.21 ----------------B9=A9-Max(A$1:A9) -------------C9=MIN(B1:B9)

Need to insert two rows, then sum column C and E based on cell value change on Column A.
...then also would like to get the summed value of each total eg,. (starting total should be where last cell should always equal the sum of first calculated cell. D6 = C6, then =C10+D6, and C16+D10, etc...) to be summed with next total down, and so forth to end (See attached)

I have a person who was paid £1000 pension pa for ten years. I've found out that the pension should have been split 50/50 with half increasing by 5% pa. Thus in year 1 total pension would be £1000. In year 2 the total pension would be £1025 ((£500 x 1.05) plus £500)
I know that in year 10 the total pension should be £500 (non increasing) plus £814 (£500 x 1.05 to the power of ten). My problem is how do I work out a formula which calculates the total arrears due in year ten? I'm thinking the arrears due after the ten years is £314 but something is telling me it's a lot more.

After about 3 hours of online research, and maybe an hour or so of experimenting with the IF command, my mind is blown and I, essentially, have given up!
I have a spreasheet with each column representing a month, then four more colums to represent quarterly values, and one other for a summary of the entire year.
I don't want a cumulative running total. For example, if I enter a value for January, that value should appear in the 1st quarter column, and yearly summary colum.
Now, if I enter in a February value, the 1st quarter column should display the February value. I need the 1st quarter column to "update" for each of the three months within the quarter. Likewise for the yearly column except, obviously, I need it to update for each of the 12 months.
I started toying with the IF function, with limited success, but there MUST be an easier way?

That means on each day the clocked hours should be compared with the actual cumulative target until that day.

I'm having difficulty with concatenation and the use of a string variable. On my attached spreadsheet I have a row called Must Fund Tasks. The binary variable in the cell is entered by a selection on a user form. If the value of the cell is "1" then that particular task must be funded. The code I developed forces solver to keep the binary value of 1 in that particular cell when looking for the optimal solution. This same row of binary variables is the row of values that I have solver change to find my optimal solution.
My problem is that I have another set of contraints based on mutually exclusive tasks. If there is a binary value of "1" in at least two of those cells then only one of the tasks may be funded and they are said to be mutually exclusive. In other words, if the user form indicated that tasks 1 and 5 were mutually exclusive then the binary values are Task1=1 and Task2=1 and the constraint would be Task1+Task2<=1. The code I've written looks for a value of 1 in the Mutually Exclusive row and if it finds one it adds the name of the corresponding "Must Fund" cell 4 rows above to a set called ExclusiveSet. ExclusiveSet is defined as a string and I'm having trouble with the concatenation, I keep geting a "+" out in front because of the intial loop when ExclusiveSet="" ( it returns "+$F$29+$H$29"). I'm also not sure if Range("CalcsStartcell").Offset(I + 15, 3).Formula = "=ExclusiveSet" is the appropriate way for me to return the value of the ExclusiveSet in the desired cell.
Sub constraint()
Dim p As Integer, CalcsStartcell As String, I As Integer, T As Integer
T = 7
I = 5
CalcsStartcell = "C16"
'setting Mutually Exclusive constraints
With Worksheets("Sheet1").Range(CalcsStartcell)
For p = 0 To T - 1
If .Offset(I + 12, p + 1).Formula = "1" Then..................
