Factor analysis is widely utilized to identify latent factors underlying the observed variables.This paper presents a comprehensive comparative study of two widely used methods for determining the optimal number of fa...
Principal component analysis(PCA),factor analysis(FA),latent class analysis(LCA),and latent profile analysis(LPA)are prominent statistical models in the social and behavioral sciences,employed to reveal underlying pat...

The inherent qualitative nature of textual data poses significant challenges for direct integration into statistical models.This paper presents a two-stage process for analyzing longitudinal textual data,offering a so...
Authority involves hierarchy and is a component of many patterns of useful collective action,capacity-building for addressing needs,and social cooperation generally speaking.However,hierarchy has its drawbacks and it ...
Drawing upon Roman public law and the classical Western ius commune generally,I sketch a law-governed constitution of hierarchy,including its institutional form and its basic justification.Grounded in a popular delega...
