Hi. We'd need a lot more information to be able to diagnose this issue. If you're performing panel GMM with a lot of cross-sections, and have fixed effects, its quite easy to run out of observations. For more detailed help, you're probably best off emailing in your workfile to us at support@eviews.c...

It won't be in the next version of EViews (EViews 7), but we have given some thought to adding more financial type procedures to EViews.

Could you give more detail on exactly what you'd want?

You can just use the wfopen command to read in Excel. In basic form:

Code: Select all

wfopen c:\myfile.xls


See the Command Reference for details on the options on wfopen to do more complicated things.

Highlight the text you wish to enclose in the codes, then hit the button - much easier.

Something along the lines of:

Code: Select all

for !i=1 to 6
    for !j=1 to 6
       equation e1_!i_!j.ls y c ar(!i) ma(!j)
    next
next


Will get most of what you want done. It won't include the zero lag options.

You'll have to compute the ICs yourself, using the determinant residual covariance to compute the likelihood.

You cannot estimate more than one equation in an equation object. You'll have to use a System.
