METANINF: Stata module to evaluate influence of a single study in meta-analysis estimation

metaninf investigates the influence of each individual study on the overall meta-analysis summary estimate. The command presents a table and a graph of the results of an influence analysis in which the meta-analysis is reestimated omitting each study in turn. metaninf is a parallel program to metainf (Aurelio Tobias; STB-47: sbe26; STB-56: sbe26.1) that uses metan (rather than meta) as its calculation engine, thus allowing access to the additional meta-analytic models offered therein. metaninf also differs from metainf in that metaninf uses metan's syntax and a subset of its options (rather than those of meta). Program mhplot (a variation of Nicholas Cox's hplot) is a required support program. This version (1.0.2) allows the jackknifed estimates to be saved. A Stata 8 dialog is included.
