var_error_q: Estimate the error variance of square roots of reliability estimates

Description

Estimate the error variance of square roots of reliability estimates

Usage

var_error_q(q, n)

Arguments

q

Vector of of square roots of reliability estimates.

n

Vector of sample sizes.

Value

A vector of sampling-error variances.

Details

The sampling variance of the square root of a reliability coefficient is:

$$var_{e}=\frac{(1-q_{X}^{2})^{2}}{n-1}$$
