st: New package -xgroup- on SSC

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

Thanks to Kit Baum, a new package -xgroup- is now available for download
from ssc. In Stata, use the -ssc- command to do this.

The -xgroup- package is described as below on my website. It is part of
a series of programs for handling resultssets (or output datasets)
containing estimation results. See Newson (2006) for more about
resultssets.

Best wishes

Roger

TITLE
      xgroup: Create a grouping variable with key values in an output
dataset

DESCRIPTION/AUTHOR(S)
      xgroup is an extended version of the egen function group(varlist).
      It inputs a varlist of existing variables, and generates as output
a
      new variable, defining a grouping of the observations by the
      varlist, and also an output dataset (or resultsset), with 1
      observation per non-missing value of the new output variable, and
      data on the values of the input variables corresponding to that
      value of the output variable.  The output dataset is sorted
      primarily by the new grouping variable, and secondarily by the
      variables in the varlist, allowing the output dataset to be merged
      into other datasets, using the official Stata command merge or the
      SSC package addinby.  xgroup is typically used together with the
SSC
      packages parmest and factext when a multiple-intercept model is
      fitted to the data, with 1 intercept for each combination of
values
      for the varlist.
