Standardized Cronbach Alpha

This node calculates the Standardized Cronbach Alpha based on the correlation provided in the correlation matrix. It uses the mean of the non-redundant correlation coefficient to describe an internal consistency of the data. Unlike raw cronbach alpha, standardized cronbach alpha is based upon the correlations rather than the covariances. The theoretical value of alpha varies from zero to 1. However, depending on the estimation procedure used, estimates of alpha can take on any value less than or equal to 1. As an input correlation model output of linear correlation node should be used.
