Exploratory and Confirmatory Factor Analysis for dichotomous variables

  • 1.  Exploratory and Confirmatory Factor Analysis for dichotomous variables

    Posted Thu July 30, 2020 02:58 AM

    I am interested in running an exploratory factor analysis for binary variables (e.g. selected, not-selected). A previous post on the forum answered something similar for ordinal variables (https://www.ibm.com/support/pages/node/418961), would this also apply for binary variables? Are there any resources in the steps to running and interpreting the output?

    Additionally, I am interested in running a categorical CFA and was wondering if SPSS has option to run that and how to go about it. If there is an option, is it possible to run it with weighted least squares?

    Take a look at CATPCA (Analyze > Dimension Reduction > Optimal Scaling. This is in the Categories option, but even if you don't have that, you can see the syntax and dialog help.
