Fellow Statalisters:

I am curious about sersets. I have read the documentation in -[P] serset- and understand a list of things that can be done with them. However, although -[P] serset- states that they are used behind the scenes by -graph-, I can find no mention of them in the -[G]- manual. Nor can I find anything by -findit serset- or -search serset- except references to -help serset- and -help file-, and the latter contains nothing about sersets except a reference to -help serset-. Are there any rare unpublicised documents, either online or hardcopy, showing examples of programs that actually use sersets? I ask mostly because I am planning the Stata 8 version of the -parmest- package, and am wondering whether a -sersetcreate()- option would be a good idea or a superfluous item of "featuritis" useful only for scaring potential users away. Such a -sersetcreate()- option would create a serset with 1 observation per fitted parameter, or per parameter per by-group, and data on a subset of the variables in a -parmest- output data set, and the user might possibly use the serset to create confidence interval plots, without destroying existing data in the memory or doing file outputs.

Best wishes (and thanks in advance)
