How To Use Sigma In Excel
May 26, 2014I 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.
this link better visualizes the formula: Browser-based, real-time TeX, LaTeX and ASCIIMath visualization
Cumulative Sum (convert Into Terms Is SIGMA)
Dec 31, 2008I 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.
Formula For Three Sigma Rule Of Standard Deviation
Sep 20, 2009I 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.
RC Notation
Jun 5, 2009I dont know why this wont work
it falls over on the ".Columns(6).FormulaR1C1=" line
Convert Formula To RC Notation
Feb 22, 2008I have got a list of formulae in column A e.g.
'=SUM(E14:E24)
'=SUM(E14:I14)
'=SUM(J14:N14)
'=SUM(Q14:Q24)
'=SUM(V14:V24)
(formulae is stored as text, i.e. preceeding with an ')
and i am looking for a VBA macro to cycle through the list and give the relative notation in column B i.e.
'=SUM(R[-11]C:R[-1]C)
'=SUM(RC[-12]:RC[-8])
'=SUM(RC[-8]:RC[-4])
'=SUM(R[-11]C:R[-1]C)
'=SUM(R[-11]C:R[-1]C)
Meaning Of Bracket Notation
Feb 9, 2007The following code was posted in another thread:
Private Sub UserForm_Initialize()
Dim a, v, x, ws As Worksheet
Set ws = Sheets("Scheduled Courses")
a = ws. Range("a2", ws.[a65536].End(xlUp)).Value
With CreateObject("scripting.dictionary")
For Each v In a
If Not IsEmpty(v) And Not .exists(v) Then
.Add v, Nothing
End If
Next
x = .keys
End With
With Me.ComboBox1
.Clear ' clear the listbox content
.List = x
.ListIndex = 0 ' select the first item
End With
End Sub
How are the brackets used in the 4th line? I have not seen this notation before. Is this some kind of a shorthand for a Range("A65536") reference?
Square Brackets - Vba Notation
Mar 22, 2007I often see square brackets around ranges in code. eg [A1]
if there are any advantages/disadvantages with using this notation, apart from the obvious its shorter?
Data Converted To Scientific Notation
Nov 3, 2008I work for a company that exports data from a website into Excel.
So here's my problem:
The data is usually Part Numbers using numbers and letters. When a Part Number is, for example, 248E12 we have this reaccurring issue. Importing it into Excel automatically converts it to scientific notation (ie. 248E+12 or 2.48E+14 to be exact). "Format Cell" doesn't convert it back because it was auto-converted when "exported". I need a way of fixing this problem without going line by line and doing the math to convert it myself.
I don't have time for that. Some of my files have thousands of lines.
Automatically Formatted As Scientific Notation
Dec 27, 2006I'm trying to filter a long list to look for specific employee numbers. The employee numbers are so long that they have to be formatted as text or they are automatically formatted as scientific notation (they are 18 digits long). For some reason this is causing the filter not to work properly.
Employee ID
006010000000000661
006015000000000082
006015000000000319

Disable Scientific Notation - Permanently, How

View 9 Replies View RelatedReferring To Range() Using Shortcut Notation
Sep 23, 2008I have noticed in many of the Excel help files that the developers liked to use shortcut notation for Range reference in VBA.
For example, Range("A1:B10") would be [A1:B10].
I was doing a bit of testing with this, and was not able to make the shortcut notation work with a variable. Does the shortcut method have the capabilities to do the equivalent of Range("A1:B" & LR)?
If it does have that capability, is it just due to force of habit that we always use Range() to refer to ranges, or would there be a more in-depth reason.
Selecting A Range Of Cells With R1C1 Notation

Code Converting Text To Exponential Notation
Dec 26, 2009I have a bit of code that is grabbing only the first 9 positions of an alpha-numeric string. The problem I am running into is that when the alpha-numberic value contains an "E", the code turns it into an exponential number in error.
For example, I have the following in column G: 01877E107000. When I run the code, it turns into an alpha-numeric value. The result should be 01877E107 (in column K). I tried using the text function within the code.
Referencing Sheet Using Cell Notation In Range
Aug 12, 2012repTot = Application.WorksheetFunction.Sum(Worksheets("Revenue").Range(Cells(xx, 65), Cells(xx, 65 + moNum)))
I am trying to debug the above line of code (moNum is just a variable the tells me how many months to extend the range to the right inorder to get year to date sums).
I have gotten to the point that it will run error free if "Revenue" is the Active worksheet when I run the line, but if I am on any other sheet it throws an "Run=time '1004' Application-defined or object-defined error" error. And if I change the range from cell notation to Column-Row, the issue goes away as well.
Conversion Of Scientific Notation To Text Not Working
Mar 13, 2013I have a large file with account numbers in Number format. Before I can import the data into a database the account numbers need to be converted to Text. I use Text(A1,0) to do this in a large file. The data then gets copied into a new Import file. When the data gets copied the account cell reverts back to scientific notation for the long account strings. The import file account column is formated for Text. The only fix is to then double click on each account that is in scientific notation to convert it back to text.
Is there another text formula I can use?
Stop Auto Format To Scientific Notation
Dec 29, 2008I run a macro that imports a table from web page:
[url]
I import only the table with no formatting.
Excel tries to be helpful, and formats some of the cells in scientific notation.
I have tried to format the column to the "Text" format prior to the import with
Columns(2).NumberFormat = "@"
This does not work. If you import the table you can see that rows 1405, 1406, 1407, 1408 all have the same scientific notation value. Their true values should be 0E0, 0E4, 0E8, 0E9 respectively.
There are quite a few other instances in the column when a text value has "E" for the second character that Excel will format on its own.
Excel 2007 :: Macro Switching Formula Into RC Notation
Oct 17, 2011I have a series of macros I have built to automate some report manipulation at my office. One of the macros I built inserts formulas into specific columns. When I run this macro, all the formulas, save one, are populated perfectly into the column they need to be in. This particular formula is swiched over to R1C1 Reference Notation.
In the workbook I built the macro in, it inserts the formula in the correct notation. When I run the macro in a different workbook, this one formula is converted to RC Notation and then is displayed as text (since the workbook is not set to the R1C1 Reference style option).
Is there a bug in my VBA code? If so, how can I correct this?
I use Excel 2007. Macros are saved in my Personal.xlsb workbook. All other forumlas populated by the macro work correctly.
