Hello All

Thanks to Kit Baum, there is now a new package -metaparm- available for download from SSC. In Stata 8, use the -ssc- command to download it.

-metaparm- is described as below on my website, and is intended for use with -parmest- and -eclplot- (also downloadable from SSC). I would like to thank Jill Starkes and Lee Sieswerda of Thunder Bay District Health Unit for drawing my attention to the example of the delta method used to calculate the confidence intervals displayed (but not saved) by -svytab-, which I have used as an example in the online help for -metaparm-.

Best wishes

Roger

TITLE
metaparm: Meta-analysis and transformations using parmest resultssets

DESCRIPTION/AUTHOR(S)

The metaparm package contains two resultsset-processing programs, parmcip
and metaparm, for use with parmest resultssets. metaparm inputs a dataset
in memory with one observation per parameter and variables containing
estimates, standard errors and (optionally) degrees of freedom, and creates
an output dataset with one observation, or one observation per by-group, and
data on estimates, standard errors, z- or t-statistics, P-values and
confidence limits for a linear combination (weighted sum) of the input
parameters, assuming that the input parameters are estimated independently
for different sub-populations. The output dataset can be listed to the Stata
log, saved to a disk file, or written to memory, overwriting the existing
dataset. metaparm is useful for meta-analyses and for calculating confidence
intervals and P-values for differences or ratios between parameters for
different subpopulations. parmcip inputs a dataset in memory with one
observation per parameter and variables containing parameter estimates,
standard errors and (optionally) degrees of freedom, and adds new variables
to the dataset, containing the confidence limits, z- or t-statistics,
P-values, and (optionally) stars for P-values. parmcip is useful if the user
requires confidence intervals for a transformation of the original
parameters.
