weighted_z | R Documentation |
Calculate the weighted z (for calculating weighted mean correlation). See p. 231 of the book Hedges & Olkin (1985), Statistical Methods for Meta-Analysis (ISBN: 0123363802).
weighted_z(z = NULL, n = NULL)
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. |
the output will be a weighted z value.
weighted_z(1:3, c(100, 200, 300))
weighted_z(z = c(1:3, NA), n = c(100, 200, 300, NA))
