st: New version of -parmhet- on SSC

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

Thanks once again to Kit Baum, a new version of the -parmhet- package is 
now available for download from SSC. In Stata, use the -ssc- command to 
do this, or -adoupdate- if you already have an old version of -parmhet-.

The -parmhet- package is described as below on my website, and (together 
with -eclplot- and the -metaparm- module of -parmest-) forms part of my 
suite of Stata programs for doing meta-analyses with heterogeneity 
chi-squared tests and Welch F-tests. The new version fixes a few typos 
in the on-line help. In particular, I have corrected the spelling of 
"Cochran", which was previously mis-spelled as "Cochrane". I would like 
to thank Nick Cox for advising me about this spelling mistake on Statalist.

Best wishes

Roger

TITLE
      parmhet: Heterogeneity tests in parmest resultssets

DESCRIPTION/AUTHOR(S)
      parmhet and parmiv are designed for use with parmest resultssets,
      which have one observation per estimated parameter and data on
      parameter estimates.  parmhet inputs variables containing parameter
      estimates, standard errors and (optionally) degrees of freedom, and
      outputs an output dataset (or resultsset) with one observation, or
      one observation per by-group, and data on heterogeneity test
      statistics on the input parameters in the dataset or by-group.  The
      output dataset can be listed to the Stata log, saved to a disk file,
      or written to memory, overwriting the existing dataset.  Optionally,
      parmhet may also add variables to the existing dataset, containing
      inverse-variance weights and/or semi-weights and/or
      semi-weight-based standard errors.  These additional variables may
      then be input to the metaparm module of the parmest package, to
      produce summary meta-analysed parameter estimates, using the
      fixed-effect method or the DerSimonian-Laird
      randomly-variable-effect method.  parmiv is a routine intended for
      use by programmers, and inputs variables containing estimates,
      standard errors and (optionally) degrees of freedom, and outputs
      additional variables in the existing dataset, containing
      inverse-variance weights and/or semi-weights and/or
      semi-weight-based standard errors and/or heterogeneity test
      statistics for the dataset or by-group.
