Estimate descriptive statistics of reliabilities from descriptive statistics of square-root reliabilities via Taylor series approximation
estimate_rel_dist(mean_q, var_q)
The estimated mean and variance of a distribution of reliability values.
Mean square-root reliability value.
Variance of square-root reliability values.
var__XX=4q_X^2var__XX4 * mean_q^2 * var_q
