st: -svy:cloglog- and margins

["Muhuri, Pradip (SAMHSA/CBHSQ)" <Pradip.Muhuri@samhsa.hhs.gov>]

Hello,

I am using the -svy:cloglog- command. Although the following code has run successfully, I find the following issues:

1) There are no results on AIC or log likelihood.
2) The covariate (category) labels do not get printed.
3) STATA has encountered memory problems with the _margins- command.

Code and part of the log file are appended below.

I would appreciate receiving your help resolve the issue.

Thanks,

Pradip

no room to add more variables because of width
    An attempt was made to add a variable that would have increased the memory required to store an observation beyond what is currently possible.  You have the following alternatives:

     1.  Store existing variables more efficiently; see help compress.

     2.  Drop some variables or observations; see help drop.  (Think of Stata's data area as the area of a rectangle; Stata can trade off width and length.)

     3.  Increase the amount of memory allocated to the data area using the set memory command; see help memory.
