Chi Squared Statistic Function
Oct 6, 2008
I'm trying to write a VBA function which performs the chi squared test (a simple statistical test to compare proportions). It works (roughly) by comparing the difference between observed values for cells in (say) a two-by-two grid, and the expected values for those cells (calculated by multiplying the row total by the column total and dividing by the overall total).
I hope to get it to work without having to calculate the expected values as set out in the CHITEST Excel function. I’m trying to convert over code which works in ASP, but I don’t think I’m calling it correctly, as I keep getting #VALUE! or #NUM!. Here's the code...

Is there an worksheet function that calculates t-stat of the regression line of 2 data series?
Say I have 2 columns of data (Y and X), I run a regression of Y on X, which gives me some slope coefficient this an be obtained by SLOPE(...) function. To estimate the significance of this slope coefficent I need t statistic. Is there a function to obtain it?
Note: I am aware that the result is obtainable from Tools - Data Analysis - Regression under the heading 't Stat'. But can I obtain it directly as a function?

I'd like to calculate the r-sqaured of the S&P 500 performance in an election year to see if that has any effect on the market's performance.
The data I have is below. The election years start in 1928 and are every 4 greater than that. How would I set it up to use the rsq forumla?
S&P 500 Index
192612%
192737%
192844%
1929-8%
1930-25%
1931-43%

Hi, as you can see in this chart I am plotting TOTAL company sales against its three merchandise components - men's, women's, and accessories. My issue is that when I had two rows to just show company sales against one of the merchandise categories -- and I Go TO TRENDLINE and show the R-Squared, it is ALWAYS THE SAME= 20%. CLEARLY, something is wrong beacuse (a) its different numbers for each of the three merchandise categories and (b) these three categories make up the total comp so CLEARLY it should be a higher R-squared than 20%. How Can I get it to properly read the R-Square.

I have a pivot table, organized by industry (with a number of companies under each industry code. I am attempting to calculate the Herfindahl index for every industry, which is the sum of squared market shares of all companies in an industry.
Current situation: I have a column sales and a column market share (which uses the information of sales and shows all items as a % of parent total, which is the specific industry; hence the market share of industry 2821 is 1).
Problem: I am trying to get the market share (so the squared value of the current market share column) of all companies in a particular industry, as I want the sum of these values for every industry.
I am aware that by using Insert -> Calculated field, you can make a formula (market share*market share), but market share is not one of the variables I can select.
Industries
Sales
Market share
2821
2,7586E+11
1,000000

I have calculated the implied volatility for different single options using the newton raphson method. But, I also need to calculate the implied volatility which minimizes the sum of squared differences between the observed market price and the model price for each day. I guess one needs to use vectors (jacobian matrix) to do this, but I do not know how to expand the code to be able to do this. Anyone have any idea how this can be done? I have attached the [code] I have used to calculate the implied volatility for one option.

When I step through my code and execute this line, the sheet is copied as expected and put in the correct place, but then instead of the next line of code being highlighted, the pointer jumps to the first line of a function (in a different module) in my code.

In Mr Excel's Pod Cast on April 12th, he showed how to use the OFFSET function to define a range inside a SUM function. Then he had Conditional Formatting that would highlight the range that was being summed. Can anyone tell me what the formula would be inside the Conditional Formatting dialog box to get the OFFSET range to have a certain format?

I have a function
VB:
Function f1(Matrix As Range)
'Does something and returns f1 = a double
End Function
And a second function which defines and constructs a matrix of doubles to use as an argument in f1 to return a double:
VB:
Function f2(dD As Double)
Dim MatrixRed() As Double
Redim MatrixRed(1 To dD, 1 To 10)
For i = 1 To dD
For j = 1 To 10
MatrixRed(i, j) = i * j
Next
Next
f2 = f1(MatrixRed)
End Function
I get an output error (#VALUE). I think it has something to do with MatrixRed not being a range anymore?

let me start by saying that I know an example workbook would be useful here, but the part I'm struggling with is the [managementroster.xlsm] file, and there is A. no way I can release it to the internets and B. its so huge/complicated I couldn't even begin to reproduce a portion of it, scrubbed of data, and hope to maintain its functionality in a meaningful manner.
[Code]....
This formula checks a staff number on this spreadsheet, and then goes and looks at the staff number on the roster. Once found, it returns that staff members roster, but changes any manager codes in the MRC list to Mgr, and changes all other roster codes to Free.
I now need this formula, before altering roster codes to Mgr or Free, to only return codes that are a match for another table (or after really. I don't particularly care, so long as only codes are shown that match data from another table). I think an index/match function would do the trick, but this forumula is already at the edge of my excel ability, nesting another function within it is completey beyond me. The relevant cells for the index/match function would be:
This first Match function targets the column. $E3 is the date required, $BA$1:$DN$1 is the range the dates are entered in
Match: Lookup value = $E3
Lookup array = '[ManagementRoster.xlsm]Vacancies!'$BA$1:$DN$1
match type = 0
This second Match function targets the row. $A$4 is the department name, $B$434:$B$452 is the range where all departments are entered
Match: Lookup value = $A$4
Lookup Array = '[ManagementRoster.xlsm]Vacancies!'$B$434:$B$452
match type = 0
Index: array = $BA$434:$DN$452
So I think my final function is
[Code] .....
But I have absolutely NO idea where it would fit within my first formula, or how to code it so that my original formula only reproduces results that are found in both sheets, or anything.

I have created a List in excel of various tasks. (See attached example.) Each row contains one cell with a function which equals the cell above it and to the right. So the function for cell C3 would be D2. The only importance is that the cell mirrored is always the cell one above and to the right. However, now I would like to be able to rearrange this List, but the “one up and to the right” function will now be all over the place.
Is someone aware of a function which will target a relative location instead of an exact cell?

I have been looking around have this much code from this site, modified. What I am trying to do is calculate numbers by a position with cells D through K having numeric values. I have 'hardcoded' the cells (D2, E2, etc in the code below), but in reality I only want the current row (so if the formula is on the 2nd row, I want D2, if it is on the 3rd row, I want D3).
My problem is obviously the formula isn't working because I am not correctly tying back to the spreadsheet (Positioncalc.xls). When I put the formula in the spreadsheet it works, but in my script I get 0 everytime.
My Script:
Function Position(rCell As Range, Optional RightPosition As Boolean)
Dim vResult
Select Case rCell.Text
Case "QB"
vResult = (2*D2) + (2*E2) + (2*F2) + (4*G2) + (2*H2) + (1*I2) + (4*J2) + (3*K2)
Case Else
vResult = "Invalid Position"
End Select
If RightPosition = True Then
Position = vResult
Else
Position = "Position not valid"
End If
End Function
So, when I put =Position(A2,True) I expect to see the formula results of those cells calculated based on the position (QB, HB, etc with their unique formulas).
My next challenge after this is to highlight certain cells based on the Position. So if A2 = QB, I want cell D2 boldface and Red, etc. I have seen some scripts on colors and such here, so I might be able to figure it out.

I have a range of cells, for this example I will use 2.
Cell E17 = 77/170
Cell E18 = 8/9
Using the following formula: =SUM(RIGHT(E17,FIND("/",E17)))+SUM(RIGHT(E18,FIND("/",E18)))
This bring back an #VALUE! Error as the second part of the formula keeps picking up "/9" however the first part works fine, displaying "170"
Now if I use:
=SUM(RIGHT(E17,FIND("/",E17)))+SUM(RIGHT(E18,FIND("/",E18)-1))
It all works. The problem is that I need this to be automatic using the above way means having to add a "-1" to every formula for a cell with only 1 char to be added.
Using the formula:
=SUM(RIGHT(E17,FIND("/",E17)-1))+SUM(RIGHT(E18,FIND("/",E18)-1)).....

I have a tracking sheet (attached) that has many functions, but I'm having trouble with two of them. First of all, I have a Worksheet_Change event set that when a cell is cleared, it fills the cell with a formula to use the record above it as a default value if another cell is equivalent. This worked when I first wrote it, but now it seems to break every other time I use it. When assigning the formula it returns a Method Default/FormulaR1C1/Offset failed error message. It seems to be different for each one, each time and I can't figure out what the problem is.
The other problem I'm having is that I wrote a BeforeDoubleClick event to expand or contract any given record, or series of records. this too worked when I initially wrote it, but now is only hiding one row when it should be hiding eight or more.
I'm not terribly versed in VBA and totally baffled as to why I'm having these problems. As I side note, any ideas to clean up any of the code and make this run smoother (as ther will be many more series added when complete).

I have a user defined function in one VBA module that I'd like to call from another module, so I would normaly scope it as "Public".
However, as I don't want it to be available to Excel as a worksheet function, I would also normally scope it as "Private"
Is there a way to have a function that is available to other VBA modules in the same project, but not to Excel as a worksheet function?

I am trying to use the vlookup function together with an offset function but i am not getting it to work properly.
The situation is as follows:
I have a column E in which i use the vlookup function to find its corresponding value in B which in turn refers to a named range. However, the figure i want the function to return is 2 columns to the right and 2 rows above the value which the vlookup funtion finds in the first column.
I have though of using the offset function, but i cannot figure out how to make this work.

I'm comfortable with the IF statements in excel and not familir with many of the other functions available to me. I am trying to create a character calulator for Elder Scrolls III (Marrowind). So that a person may enter their race, ***, and other choices and their by calculating all starting stats. There are 10 races you can choose from and I can cover 9 of them with the if function (leaving one as if all other options are false). I would like to know if there is a better way such as a drop down list or some way to search an array or anything that would be better suited to search the race cell and return data if it's true. I'm running into the same probably with choosing the constalation (13 choices in this catagory).
I thought to split it two different data fields, by letting you choose from 4 in one cell and the other 9 in a different cell, but realized I don't know how to make it check two different cells for a choice to return it to the display cell without hitting the limitation of the 7 nested funcations in a forumla again.

I am using the COUNTA function which works great but I also have data that I dont want counted and do not know of the problem solver.
E.G
in B1 I have vlookup function thats brings back either "B", "C" or "M".
in c1 I have =IF(A1="C",B1,"")
Now, that tells me if the data is B or not. If it is, it says B If it isnt, its blank
Thats great but when im trying to count how many "B"'s there are, it counts the blanks as well!

I am using COUNTIF functions with Defined Name lists to quickly determine if a certain number is on a list. As a backdrop, I am using Chemical Abstract Service (CAS) numbers and attempting to somewhat streamline chemical approval for a small company. CAS numbers are often in the format of XX-XX-X with varied amounts of numbers. One of the defined lists however does not have dashes.
Thus, I am using cell B1 to enter the CAS# once and then for each list having a column to itself with an associated worksheet with a defined name list. Most of the columns have the function =B1 with the conditional formatting of =COUNTIF(definedname,BX) and formatted to turn red if the chemical is on the list. This is working for all of the columns except for the list that needs the dashes removed. For instance, CAS 64-67-1 is put in B1 and cell B5 has the formula =SUBSTITUTE(B1,"-","") which brings the number to 64671 which matches the number in my defined name list. However, the cell will not turn red. What am I missing?
