meta.ave.slope

Computes the estimate, standard error, and confidence interval for an
average slope coefficient in a simple linear regression model from two
or more studies. A Satterthwaite adjustment to the degrees of freedom
is used to improve the accuracy of the confidence interval.

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:
