See p. 231 of the book Hedges & Olkin (1985),
Statistical Methods for Meta-Analysis (ISBN: 0123363802).
Usage
weighted_z(z = NULL, n = NULL)
Value
the output will be a weighted z value.
Arguments
z
a vector of z values
n
a vector of sample sizes which will be used to calculate the
weights, which in turn will be used to calculate the weighted z.
