If it is SSM, at what stage should I apply it? Or is there another SAS procedure? Thank you for your help. jhkim Maybe you should be providing an example and interpretation of what you think a "factor analysis" of a single variable would look like. Or what you mean by "factor". There are multiple procedures in SAS that do factor analysis but perhaps you meant something other than formal factor analysis in those terms. I am in charge of implementing the contents of research in the research institute into SAS The lab uses Python, and there is a DFM model in Python, and it was analyzed in this way. The data consists of only the X variable, and the first principal component common factor was calculated using Python DFM. I was worried about the implementation of this process, and I made an inquiry. So, is the procedure SSM or Factor? Thank you for your help. jhkim
