This thread is about the EqTabs Add-in that allows you to organize the output from the equations in your workfile into one table.
Change Log
  • 2010/04/05 - Initial Release
  • 2010/09/09 - Change to EqStackTab to display dependent variable names
  • 2010/09/27 - Change in EqSumTab to allow a list of equations to be entered from the command line.

EViews crashes (shuts down completely) when we try to use the "summary" option on certain files. The files have about 20-30 equation objects and 400,000 rows of data - is this a memory issue? Is it possible to change the program to clear the memory cache after it runs each regression? Or better yet, could it just take the output from all the regression objects instead of re-running the regressions during the program?

It doesn't re-estimate the regressions. Could you post an example workfile where EViews crashes?

Hello Gareth,
It is very helpful program, thank you

I used EqTabs stack table version for AR MA model (ls y c ar(p) ma(q)) but it did not give the probability values of AR and MA coeffcient, it just gives C's probability. How can I get probabilities of AR and MA coefficienst?
Thanks

Yeah, neither program support ARMA terms.

At the time I wrote them there was no way to obtain the ARMA term information from an equation. Since then I've added the equation.@armaspec data member which lets you retrieve the ARMA information. Thus at some point it would be possible to update these programs to support them.

If someone wants to add it to them, great. Otherwise I'll look into it next time I have time.

Hi Gareth,

Is there a way to add an option to show the dependent variable? I see the @coeff and @stderrs in the program but cannot figure out what the command is for showing the dependent variable.

Yeah, that one doesn't have that option. I'll contemplate adding it.

EQSumTab does show the dependents

Thanks. The SumTab would be preferred for what I do, but it seems to crash everytime I run it. Then again, it's on 370+ equations with 10-12 variables a piece. Could it be a memory issue?

Would it be possible to upload your workfile?

I can't, however if you'd like to do a Go to Meeting at some point so that you can see my screen we can set that up. Email me at elimoore@cmgconsulting.net

EqStackTab has been edited to all dependent variables.

I found that the output table name is "results". Say, in the source code

Code: Select all

%tabname = "results"
if @isobject(%tabname) = 1 then
%tabname = @getnextname(%tabname)
endif

why not add an option to pass the table name? (and the default name can be "results" or "untitled" ...)
