Subject | st: New version of -parmhet- on SSC |
Date | Mon, 2 May 2011 16:11:07 +0100 |
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.

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.
