q_stat_test_homo_r {kim}

Q statistic for testing homogeneity of correlations

Description

Calculate the Q statistic to test for homogeneity of correlation coefficients. See p. 235 of the book Hedges & Olkin (1985), Statistical Methods for Meta-Analysis (ISBN: 0123363802).

Usage

q_stat_test_homo_r(z = NULL, n = NULL)

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.

Value

the output will be a weighted z value.

Examples

q_stat_test_homo_r(1:3, c(100, 200, 300))
q_stat_test_homo_r(z = c(1:3, NA), n = c(100, 200, 300, NA))
