I am wanting to write a macro which uses the excel multiple regression function (a part of the data analysis add-in). I tried recording a macro while I selected the regression function (Tools> Data Analysis... etc.) which produced the following:
I'm trying to write a macro that will analyze data from one spreadsheet and do a regression. The information I want to be output on the same sheet. I tried to use the record function, but I got an error. It said "Run-time error '1004': ATPVBAEN.XLA could not be found. The code read:
I was handed the attached file. understand everything except how the values in row 6 were derived No formula present when I received the file, just the numbers. Row 7 is hard entered scores the units achieved
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?
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?
I have one question about the regression. i know how can i do it lineair, exponentiel ... but how can i make a personnalised regression ? for example, if i have i function f(x)=a+b*x^2 or another function ... how can i introduce my function to draw the regression ? i have excel 2007
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?
I have a set of data. I know how to do linear regression over the whole set of data. How do I have another linear regression over the first 5 points in the set of data on the same graph ?? I am using Excel 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.
However I have a subject at uni that requires me to create a series of regression models, histograms, correlation matrices etc.
For part of the assignment, i have to run 4 regressions (one for men & one for women) with dependent variable as average wages, and independent as bfast 1,2,3 and dinner 1,2,3 (all of which are dummy variables) (0 for male and 1 for female).
The second two regressions are exactly the same, except average wages must be transformed into log which i have already done.
I dont know how to differentiate the regression models into male and female (if possible). We must also include residuals and residual plots.
I keep getting an error that says non-numeric data, the other says input range must be a contiguous reference.
I have 2 macros one hides a selection of rows and the other unhides them. What i want to be able to do is when an IF function is true then macro 1 (hide) is used. If the function is false then macro 2 (unhide) works. There is a code in VBA
What I would like to do is create a macro (use a shorcut key to activate ie crtl+q)or if there is a barcode I could scan to do that when the function is called for it would move down one cell then left 4 cells. I am looking to to this when walking around doing some scanning I could do that function rather than pressing the keys all the time.
I'm having a little problem with the function Sumif. I have data like this:
Date 0 0
Total 0 78[code]...
I want to some all the Totals that appear before the "End Notification" text. I have more totals after that text and the number of rows are variable.
In my data, I have always 4 totals before that text, so I thought perhaps that the way to do this would be to impose to the sumif function to stop summing after counting 4 totals. I didn't find a way to do that.
I thought a little more on the problem and I find out that the easy way would be to record a macro with the sum if function, where, in the range part, I would do a Find for "End Notification"; and select all the cells to the top of the sheet. The problem is that the macro dont record that part, only the row number.I think I need to turn the range a variable, where the variable is equal to the find selection.
I have a quote system which takes data from tabbed sheets if there value is greater than 0, then does a simply formula which is then times by a discount which found by searching for the sheet name and then attaching the appropirate discount. In short this means that the whole forumale doesn't work and is not displayed
It then places all the data on a new sheet. My problem is that some of the formula that the macro places on the new sheet come back with the result #N/A - which is fine, as they are the result of a lookup.
What I want to try and do, is at the end of the macro, get it to delete the row if the activecell is showing as #N/A
I am trying to use the Vlookup function in a macro but I can't figure out how to write it. I am using a controlled loop to cycle through my data. So for the first entry, my lookup data is in cell A2. The lookup table is located in a sheet called 'Trade Table' and the lookup field is in Column B and value needed is in column C. The results go in column G. The excel formula is as follows:
