test.tauequivalence: Test the essential tau-equivalence of the data

In eunscho/reliacoef: Compute and Compare Unidimensional and Multidimensional Reliability Coefficients

Test the essential tau-equivalence of the data

Description

The goodness-of-fit indices are compared with the parameter estimates of the essential tau-equivalence model and the cognate model. It can also be used for the purpose of investigating the unidimensionality of the data.
