multiSub

group

<p>This sub-routine outputs TRUE if either <code>i</code> or <code>j</code> are in 
<code>group</code>, FALSE otherwise, and is called by <code>matrixStrucTest</code> 
and <code>prepBoxPlots</code>.</p>

Tests for block-diagonal structure in symmetric matrices (e.g. correlation matrices) under the null hypothesis of exchangeable off-diagonal elements. As described in Segal et al. (2019), these tests can be useful for construct validation either by themselves or as a complement to confirmatory factor analysis. Monte Carlo methods are used to approximate the permutation p-value with Hubert's Gamma (Hubert, 1976) and a t-statistic. This package also implements the chi-squared statistic described by Steiger (1980). Please see Segal, et al. (2019) <doi:10.1007/s11336-018-9647-4> for more information.
