Re: st: Recovering Names of Factor Variables for Displaying Table of Estimates

["Roger B. Newson" <r.newson@imperial.ac.uk>]

One possibility is to use the -parmest- package, downloadable from SSC, 
to create a dataset with 1 observation per estimated parameter and data 
on parameter names, estimates, confidence limits, P-values and other 
parameter attributes.

If you use -parmest- to create such a dataset, then you can also use 
-fvregen- to reconstruct the factors corresponding to these parameters 
in the output dataset. And you can use -descsave- to reconstruct the 
variable labels, value labels, storage types, formats and 
characteristics of these factors. You can then -list- the dataset, 
displaying the factor names and values. And you can also plot the 
confidence intervals and P-values, if you want.

The -descsave- and -fvregen- packages are also downloadable from SSC. An 
example of the use of -fvregen- is given in Newson (2010).

I hope this helps.

Best wishes

Roger

What I cannot figure out is how to reference the names of the newly-created two-way multiplicative interaction terms.  I have even tried to copy the variable names from - mat list e(b) - .  That works for the simple, one-way dummy, but not for the interaction terms.  Is there a simple solution?
