Multiple Linear Regression In VBA?

Oct 16, 2008

I would like to run a multiple linear regression in vba. I have one dependent and three explanatory variables. I will have to use a macro of some kind, since I need to run too many regressions to do it manually. To simplify things a little bit:

- There will always be exactly three independent variables

- There are no missing values

- The data is allways numerical

I've already got four ranges defined: Yrange, X1range, X2range, X3range. I would like to take these ranges as input parameters for the regression model. The only two parameters I need are Sum Square for Regression (SSR) and the degrees of freedom. I understand that you can use excel's matrix formulas to calculate some of the input parameters, but one doesn't really get around vba. Any (simple) source code allowing me to conduct a regression with three input parameters?

Linear Regression Array - Significance Of R Testing

May 5, 2014

I have set up a linear regression array in Excel and now want to test the significance of my r2 value at a certain level of significance. I've only been able to find tables that give the critical r value, but I want to test it at 99.73% level of confidence and none of them contain that specific value. Is there a way to do this in Excel?

Constrained Regression Using Solver

Nov 11, 2008

I have the following dataset and was wondering how I can run a constrained regression in Excel with the constraint being that the total allocation of assets is 100%:

Total return (y): 12 data points
Asset 1 (x1): 12 data points
Asset 2 (x2): 12 data points
Asset 3 (x3): 12 data points
Asset 4 (x4): 12 data points
Asset 5 (x5): 12 data points
Asset 6 (x6): 12 data points

[Attached is a spreadsheet with the actual dataset]

I know the regression equation I need is R = b1X1 + b2X2 + .+ (1 - b1 - b2 -.- b5 )X6 + e

Quadratic Regression Calculation

Feb 8, 2007

I am trying to set up the formula y = ax^2 + bx + c. Is there a function for that in excel?

To get a little more into my overall goal. I will have a x constant that will remain the same, but I have 8 different sets of a,b, & c coefficients. So, I would like to set up something like, if a row is labeled A1, find the A1 set of coefficients and use them in the quadratic equation. I was thinking I would need to use a CSE, is that correct?

Duplicate Numbers On Single Row?

Mar 3, 2012

With exception to Duplicate numbers on a single row, or column. I am hoping I can check an entire row against other rows, to see idf the same number are repeated.

Unlike the Lotto, this is about Safety boxes, where I have sequential numbering such as the following:

Row16: 2,8,12,17,18,33,
Row102: 2,6,8,14,22,44
Row645: 2,6,8,14,22,44

Notice rows 102 and 645

I can't believe all of our staff missed the duplicate lines 102 and 645 of duplicate Although these row numbers were rows 2, 16, 102, & 245

Multivariate Polynomial Regression In Excel?

Feb 8, 2010

I am trying to do multivariate polynomial regression in excel, trying to correlate data of the form y=f(x1,x2) with second order polynomials:

Y = c + a1*x1 + a2*x1^2 + a3^x1^3 + b1*x2 + b2*x2^2 + b3*x2^3

Using the following command, I have achieved this:

=LINEST(A2:A10,B2:B10^{1,2,3,0,0,0}*C2:C10^{0,0,0, 1,2,3},TRUE,TRUE)

theory Excel uses for this kind of regression?

Convert Numbers To Single Letters

Jun 8, 2007

In row G, I have a wide range of values from -3000 up to 2500.

These values are generated from a formula. =A5-B5.

I need a script that will scan row G between G5:G500 and give them a letter value.

Convert anything less than 0 to an A
Convert anything equal to 0 or equal to 1 to a B
Convert anything between 2 and 7 to a C
Convert anything greater than 7 to a D

It can place the new categorized letter value over the original formula in row G or put the letter value right next to it in H.

Join All Non-Zero Numbers Of Range Into Single Cell

Apr 11, 2008

I am trying to write a macro that will select and copy all cells in a row that do not have a zero value.

The data I am trying to select will be contained in 12 cells in a single row, i.e cells A1:L1 and all zero values will always be on the right hand side of the first non-zero value in this row (going left to right), for example:

Row: A B C D E F G H I J K L
(1) 0 0 0 0 1 1 2 2 2 2 2 2

What I want to do here is to select and copy cells E1 to L1, since they are the cells with non-zero values. This can vary, so here there are 8 cells with non-zero values but the next time there might be only 5 cell or all 12 cells, etc. I have a lot of data to sort like this so doing this manually takes a lot of time.

Once the macro has selected and copied the right cells, I will manually paste the data where I need to put it.

The big problem I am having is knowing how to firstly select the appropiate cells.

Print Consecutive Numbers In Single Cell

Jun 5, 2008

I have set up a spreadsheet template that automatically populates specific values through the spreadsheet based on what the value of cell "A1" is. I want to run through 224 potential values in cell A1 and print out the worksheet after each potential value.

My thought on how to approach it is to write a macro that:
1. Selects the next item from the drop down box in cell A1
2. Prints the page (using default print settings)
3. Loops

But I don't know what the code would be. Cell A1 also does not need to be a drop down box, as long as it incrementally runs through all 224 listed values and prints after each one.

Linear Interpolation

Feb 10, 2007

need an excel simple formula or function that returns values of y for given x in a two-dimensional array and works in the following way.actually a combination of linear interpolation and lookup/linear search. as in following example

x y
1 10
2 15
3 20

if x=1.5 then y=12.5 (answer available thru FORECAST but incomplete)
if x=2 then y=15 (answer available thru LOOKUP but incomplete)

so for whatever the x i need/get a valid y thru a single formula/method !
sorry m not good in math,

Regression Coefficients Estimated Incorrectly When Centered Predictors Used

May 23, 2007

to getting accurate regression coefficients from a dataset with *small* (standard) numbers, which contains centered predictors. More specifically, I have a dataset with 18 observed data points containing a criterion (y), a centered predictor variable (x), another centered predictor variable (z), and the interaction of the two centered predictor variables (xz). This multiple regression equation is structured to test for interactions between the two continuous predictor variables (x and z) as prescribed by Aiken and West (1991) in their classic book.

When I run the regression in Excel with the centered predictors, some of the regression coefficents in the output are estimated to be 0, although they are clealry *not* 0 as estimated by SPSS 14.0.2. I have spent many hours troubleshooting this problem (and searched many forums on the internet) and still do not know why this is happening.

Initially, I thought the problem might have to do with the cross-product of the centered predictors, but even just doing a regression with one of the centered predictors (for certain centered predictors) yields a regression coefficient of 0 (although it should be non-zero as per SPSS 14.0.2). When doing these multiple regressions with non-centered predictors, all regression coefficients are estimated accurately.

I was wondering if anyone had any insights on why I am experiencing these problems.... If anyone wants a sample of some test data I have used to troubleshoot these problems, you can download a file from: [url] and/or email me at (email deleted by Mod) for more datasets or questions.

Identifying Missing Numbers And Updating In Single Cell

Jul 9, 2014

As i am working on consolidating the Missing numbers manually, whether will it possible for making this automatic.

In Column "A" I have Multiple Duplicate Invoice Numbers and followed by the Different Transcation numbers in Column "B".

In Column "D" I have Each Invoice Numbers and in Column "E" Total Transaction Numbers i.e., no. of times each Invoice have Transactions.

In Column "F" No. of times we received the Transactions.

Here i need to manually need to update each Invoice's Missing Transaction number in Column "H" in single cell with comma separated to each Missing Transaction numbers.


Before : (Column "A" & "B")

Invoice NumbersTransaction NumbersInvoice NumbersTotal Transaction NumbersReceived Transaction Numbers
A2014000351501 A201400035150 3 2
A2014000351502 A201400035494 13 12
A2014000354941 A201400035881 12 11
A2014000354942 A201400035884 19 17
A2014000354943 A201400035888 14 13
A2014000354944 A201400037613 5 1


Instead of doing this manually can we have the VBA to auto Update these missing numbers.

Here by i am attaching sample file.

UDF - Find Consecutive Numbers In Single Cell With Dash

Mar 14, 2014

I need find consecutive Numbers in a singles Cell but each numbers have a leading zero and "-" (Dash)

My problem is that the UDF that i found on this forum, is for numbers with out leading zero with comma ",",

So even if change the "," by "-", still getting a error Because the Code is designed to Read numbers Formats different than mine..

My Numbers are located in Cell G12 (down), and the message that i need to show in the cell result is :

If Found :
0 Consecutives --> 0
2 Consecutives --> 2
3 consecutives --> 3
4 consecutives --> 4
5 consecutives --> 5
2 Set of consecutives --> 2S

Example of 0 consecutives --> 01-04-07-12-25-30
Example of 2 consecutives --> 01-02-07-12-25-30
Example of 3 consecutives --> 01-02-03-12-25-30
Example of 4 consecutives --> 01-02-03-04-25-30
Example of 5 consecutives --> 01-02-03-04-05-30
Example of 2 sets of consecutive s --> 01-02-07-12-25-26

BTW my numbers start on Cell G12 down..

VLookup Work With Multiple Numbers Within A Single Cell

Aug 15, 2009

I built an Excel Macro to pull information from my schedule and compile it within another Worksheet. The Macro below searches for an instance of "Unavailable" and then populates my Data Worksheet with the WeekDays (ie: M-W-F or ALL Week), the Details (ie: Vacation or Training) and the Name of the employee. I struggled with a way to populate my employee name as "unavailable" isn't always offset by the same amount of characters to employee name (as it is with WeekDays and Details). Instead, I collected the row in which "Unavailable" was found.

I used the Vlookup function to populate the number of Absences and it worked swell.


C2 is populated with Weekdays (ie: ALL week or M-W-F)
O contains a list of possible day combinations
P contains the number of days

I hoped to use a similar function to populate my employee names. This didn't work well a 'tall.
