Obtain stratified alpha reliability estimates of two-dimensional data

Description

Obtain stratified alpha reliability estimates of two-dimensional data. It is a multidimensional version of coefficient alpha. Items should be grouped by each sub-dimension. For example, the first dimension consists of the first item through the until item.

Usage

stratified_alpha(x, until, mp = FALSE, print = TRUE)

Arguments

x	observed item scores or their covariances
until	The number of items up to the first sub-construct
mp	if TRUE, print multidimensional parallel reliability estimates
print	If TRUE, the result is printed to the screen.

Value

multidimensional_reliability a stratified alpha reliability estimate

subdimensional_reliability reliability estimates of subdimensions

omega hierarchical general factor saturation
