Comparison of principal component solutions in two populations [Elektronski vir] : a bootstrap test of the perfect congruence hypothesisSočan, GregorWhen principal component solutions are compared across two groups, a question arises whether the extracted components have the same interpretation in both populations. The problem can be approached ... by testing null hypotheses stating that the congruence coefficients between pairs of vectors of component loadings are equal to 1. Chan, Leung, Chan, Ho, and Yung (1999) proposed a bootstrap procedure for testing the hypothesis of perfect congruence between vectors of common factor loadings. We demonstrate that the procedure by Chan et al. is both theoretically and empirically inadequate for the application on principal components. We propose a modification of their procedure, which constructs the resampling space according to the characteristics of the principal component model. The results of a simulation study show satisfactory empirical properties of the modified procedure.Source: Methodology [Elektronski vir] : European journal of research methods for the behavioral and social sciences. - ISSN 1614-2241 (Iss. 1, Vol. 12, apr. 2016, str. 11-20)Type of material - e-article ; adult, seriousPublish date - 2016Language - englishCOBISS.SI-ID - 60468066
