meta.sub.spear

Computes the estimate, standard error, and confidence interval
for a difference in average Spearman correlations for two
mutually exclusive subgroups of studies. Each subgroup can have
one or more studies.

Implements functions for varying coefficient meta-analysis methods.
These methods do not assume effect size homogeneity. Subgroup effect size
comparisons, general linear effect size contrasts, and linear models of
effect sizes based on varying coefficient methods can be used to describe
effect size heterogeneity. Varying coefficient meta-analysis methods do not
require the unrealistic assumptions of the traditional fixed-effect and
random-effects meta-analysis methods. For details see:
