16 Νοε 2022 · Factor analysis. Stata’s factor command allows you to fit common-factor models; see also principal components . By default, factor produces estimates using the principal-factor method (communalities set to the squared multiple-correlation coefficients).
Factor analysis is used mostly for data reduction purposes: To get a small set of variables (preferably uncorrelated) from a large set of variables (most of which are correlated to each other) To create indexes with variables that measure similar things (conceptually). Two types of factor analysis. Exploratory.
This page shows an example factor analysis with footnotes explaining the output. We will do an iterated principal axes (ipf option) with SMC as initial communalities retaining three factors (factor(3) option) followed by varimax and promax rotations.
Factor analysis, in the sense of exploratory factor analysis, is a statistical technique for data reduction. It reduces the number of variables in an analysis by describing linear combinations of the
9 Σεπ 2021 · This is a concise, easy to use, step-by-step guide for applied researchers conducting exploratory factor analysis (EFA) using Stata. In this book, Dr. Watkins systematically reviews each decision step in EFA with screen shots of Stata code and recommends evidence-based best practice procedures.
Factor analysis can be seen as a method of data reduction, which is rather different from other methods presented in this guide. This part focuses entirely on factor analysis, and also includes a section on how to assess internal consistency with Cronbach’s alpha.
