unirel: Obtain various unidimensional reliablity coefficients

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

Obtain various unidimensional reliablity coefficients

Description

R packages that provide unidimensional reliability coefficients include Lambda4 and psych. These are usually separate functions, so comparing multiple reliability estimates can take a long time. This function shows the reliability coefficients newly added in this package together with the reliability coefficients provided by Lambda4 and psych. This function can provide Table 2 of Cho(in press) immediately.

Usage

unirel(x, Lambda4.include = TRUE, psych.include = TRUE)

Arguments

x	a dataframe or a matrix (unidimensional)
Lambda4.include	Whether to include the reliability coefficients provided by the package Lambda4 (lambda5, lambda6, max_lambda, lambda4_max, lambda4_75)
psych.include	Whether to include reliability coefficients (GLB.algebraic, GLB.fa) provided by the package psych
