I have instances where my Y variables sometimes contain a zero in the data and i need a formula to skip over that data point in the LINEST calculation.
Y variables are in Row 1, Columns A:E
X variables are in Row 2, Columns A:E
The following formula is returning a #VALUE! error: .....
I'm trying to implement the linest formula in a programming language for my coursework.
I've looked on excel help but it only explains on how the function selects data.
how to the values are calculated and the steps?
I can do least squares fitting utilizing LINEST and a worksheet. (See attachment.)
I would like to do the same calculations entirely within VBA.
I can specify the values as arrays within VBA :
Sub linest2VBA()
'
' linest2VBA Macro
'
' Keyboard Shortcut: Ctrl+Shift+A
'
Dim dXvalSqd(4), dXval(4), dYval(4), dFirstRegStat As Double
Dim i As Integer
Second Question:
Is there a way to get the remaining regression statistics within VBA by referencing only the three arrays: dXvalSqd, dXval, and dYval?

I am trying to come up with a formula that will allow the commission calculation to be done automatically once data is inputted in cell A2 and E2. I have tried IF statements, but can not figure out how to make it work. I am not able to figure out how to get cells F9 and F19 to work with the proper formula.
View 4 Replies View RelatedI am trying to link the cells up in a new workbook the problem is the data I need is setup in a way the formula needs to skip every other row.
For example:
I have a pivot table as shown below which is pretty straight forward however I am trying to create a macro that will automatically change the point name to match the point name in column E then copy that resulting dispaly to another sheet then pick the next point name in line and do the same thing and repeat for 50 rows, so my end result will be 50 pivot tables ready for printing. I can do this manually but I am trying to make it automatic...BTW the point names in column E change everyday but the pivot table supports the name changes.
Option Explicit
Sub PointName()
Dim Ws As Worksheet
Dim Rng As Range, Cel As Range
Set Ws = ActiveSheet
Set Rng = Range(Cells(2, 7), Cells(Rows.Count, 7).End(xlUp))
For Each Cel In Rng
Ws.PivotTables("PivotTable1").PivotFields("Point Name").CurrentPage = Cel & " "
Ws.Columns("A:B").Copy
Sheets.Add
With ActiveSheet
.Paste
.Name = Trim(Cel)
.Range("A1").Select
End With
Next
Ws.Activate
End Sub
I turned it off for a while and when I turned it back on I am getting an error
Unable to set the _Default property of the PivotItem class

I want to make the formula: x=SUM(A * e^(-b*d)), wherein A and b are parameters and d the distance.
I've just over 10.000 rows and 15 columns (B4 to P10013) with distances. For each column i give a formula =$S$2*EXP(-$R$2*B4) and extent that for all colums and rows, then I sum all the columns. This works fine, except for the fact that when there is an empty cell the outcome is wrong. Because I set for example A as 10. The answer for that cell is 10, because he sees an empty cell as 0, i guess.
So how do I skip these empty cells?
I'm looking to create a formula that will skip past any blanks until it finds the latest and most up-to-date value.
Some context: I wish to return a latest estimate value to a cell (A5), and this value is updated quarterly. Let's say that the quater 1 value sits in cell A1, Q2 in A2, Q3 in A3 and Q4 in A4. I wish cell A5 to display the latest estimate as soon as a user updates it on a quarterly basis, but default to the previous quarter's estimate if that latest view is unavailable.
I've tried using some IF(ISBLANK...) combinations but am getting nowhere !
NB want to try and avoid Macros across this worksheet so a formula solution would be best.
This formula holds good for regular offsets (7 cells).
how to copy a formula that skip rows?
How to get the values from irregular offsets...??

I have the following formulae in seperate cells were A1, A2 and A3 are the cells
A1 =MAX(Data!C2:C3)
A2 =MAX(Data!C4:C5)
A3 =MAX(Data!C6:C7)
I would like to drag the cells so that automatically the cells below A3 are updated as follows
A4 =MAX(Data!C8:C9)
A5 =MAX(Data!C10:C11)
etc up to 600 rows
Unfortunately it is not being updated in that order. Do you have any suggestions how it can be done.
I'd like to point a cell to a subtotal on another sheet but that sheet will periodically have the subtotals removed, more data added, then sorted and subtotalled again. Is there a way to have my other cell find the subtotal that matches a certain criterion (in this case, cost center)?
View 9 Replies View RelatedI have a spreadsheet which contains data for crime incidents occurring in a month. I have created a worksheet which uses "IF" statements to pull in data that occurred within the last 24 hours only. I would like to create a report that can be printed which has a crime category and lists all the incidents for that category below that occurred during the day. The issue I am having is that all "IF" and "LOOKUP" statements are line for line and I want to be able to skip blanks or where it is not the category in the title.
View 4 Replies View RelatedI am trying to find a formula that will allow me to reference another page in my spread sheet. In my scenario the row I am referencing has 5 consectutive numbers after the reference point I would use for a vlookup. These numbers are all zeros except for one number in each row which will be a positive number greater than zero. I want my formula to check the first cell in the row, if it is not a zero it will show that number, but if this cell contains 0, then it moves over to the next cell. If all the cells in the row have a zero, then i just want zero to appear on my summary sheet. I tried to do a vlookup with an IF function, but I couldn't get it to work. I have attached a sample of what the spreadsheet looks like.Example doc.xlsx

Code:
Column A Data:
007-006
007-006P
008-008
008-008P
Column F Data:

{=SUM(IF(RIGHT(TRIM(A4:A23),1)="P",0,F4:F23))}
When a row is inserted above row 24, the formula does not automatically include this row.
When this cell formula is modified manually, I get an error, unless I save the formula by pressing CTRL+SHIFT+ENTER.
How can I make it so that when a user inserts a line above this formula, to add more data, I can make sure that the formula automatically includes this row so the user will not get an error when trying to manually include this row. Users who will use this will know know this is a Array Formula.

Pivot Chart. I would like to set up something to where a user can click on an individual value on a pivot chart (currently a line chart set up with 4 data series) and somehow display some underlying data. I have a lot of information stored in a data worksheet that I can't display all at once, but if a user sees a questionable data point, he/she can click and learn more about it from source data, or even a new query of the data worksheet.

I have set up a formula to sum data from specific columns in multiple sheets in the same file. The simple formula had worked perfectly until I needed the data from the last sheet. In all of the other sheets the data that I need to pull is all in consecutive rows but in the last sheet the data that I need pulled and added is in every 4th row. The sheet looks like this:
All of the columns I've filled in work fine. The ones blank are the ones I am running into issues with. When I drag down the formulas excel pulls the next consecutive rows, which is perfect for the first four sheets I am summing, but for the fifth sheet (I'll ref the Test1 column) I need it to pull 'Wayne 2014'!C6 and then 'Wayne 2014'!C10 in the next row and so forth.

I want to use a Pivot table to filter data to show just the studies that contain patients from the 'South' area?
As per example below I want to be able to see all the patients in all areas but only for studies that have patients from the south. I put together an array formula that works well for small tables but is too much with one one my sheets that contains 200,000 rows.

Is it possible to Conditionally Format using the (Custom) Data Validation Tool one or both of the following conditions:-
1. Force the user to enter the correct decimal point position for a given currency :-
The are 3 different decimal point locations location's - 0.87624 / 123.123 / 1273.00 There are always 6 numerals We have a table to lookup which specifies where the decimal point is on all currencies
CURRENCY AUDUSD< List is linked to a table
Price - High 0.87744< Decimal point dependant on chosen currency pair chosen
Price - Low 0.86596
Price - Close 0.86823
2. As above but numbers once entered will be formatted accordingly to the correct decimal place to the corresponding currency

I am using Excel 2007. I have two sets of data. y-series is 58.61, 58.66, 58.71 and 58.76. x-series is 0.8313, 0.8309, 0.8305 and 0.8301.
I am trying to fit a quadratic function to this data. When I plot a curve and fit a trendline I get the coefficients for the equation ax^2+bx+c
a=1.3939e-11
b=-125
c=162.5225
The plotted line seems to fit the data fairly well.
However, I want to use the linest function and I am using the formula:
=INDEX(LINEST(B2:B5,A2:A5^{1,2}),1,1)
I change the index column number as appropriate to get the coefficients:
a=-75.23775
b=0
c=110.603763
The coefficients from linest seem to be way out. how I can get the output from linest to be the same as the trendline?
My "calculated" polynomial is not the same as the Trend line on the graph. The one on the graph seems to be correct.
Basically, I am using the LINEST function to create a polynomial equation inorder to extrapolate data. And also with a given equation, and a given y, find x.
I am calculating variables in Vba and want to find their co=effiicients in the for y=a +bx +cx^2. This works great if I output my variables to excel and then pick up this range however as I am generating the variables in vba and have an array of variables I would rather not have to keep spitting them out to excel then picking them up again. The three important lines in my code are:
c(nFix - j) = WorksheetFunction.Index(WorksheetFunction.LinEst(inpv, Application.Power(inps, Array(1, 2))), 1)
b(nFix - j) = WorksheetFunction.Index(WorksheetFunction.LinEst(Range(Vc), Application.Power(Range(SPd), Array(1, 2))), 1, 2)
a(nFix - j) = WorksheetFunction.Index(WorksheetFunction.LinEst(Range(Vc), Application.Power(Range(SPd), Array(1, 2))), 1, 3)
As you can see for c I am referring to inpv and inps these are arrays. I have tried using inpv(), etc but no luck
b and a work great, here I am reffering to ranges Vc and SPd. As I am going through this a lot of times it seems rather inelegant not to be able to do the whole thing in vba - i would rather not use the dump to spreadsheet then pick up again approach!
