Graham1: Graham's (2006) first unidimensional data

In eunscho/unirel: Compute and Compare Unidimensional Reliability Coefficients

Description

Graham's (2006) artificial dataset consisting of five items.This is the second dataset in his Table 2. The last item is about five times as important as the other items. This dataset provides a good indication of how sensitive each reliability coefficient is to the violation of the tau equivalence assumption. The CFA reliability coefficient presented by the author is .97.

Usage

Format
