se.biphi

Computes an estimate of a biserial-phi correlation and its standard error
using the frequency counts from a 2 x 2 contingency table where one variable
is naturally dichotomous and the other variable is artifically dichotomous.
The biserial-phi correlation approximates a point-biserial correlation
between the naturally dichotomous variable and the unobserved quantitative
variable that was measured on a dichotomous scale. A biserial-phi correlation
biserial-phi estimate and the standard error from this function can be used
as input in the meta.ave.cor.gen function in a meta-analysis
where a point-biserial correlation has been obtained in some studies and
a biserial-phi correlation has been obtained in other 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:
