Solved – Testing for validity of a formative measurement model

confirmatory-factorspss

I have developed a formative model which tests the relationship between two composites.

Obviously, I have to ascetain the validity of this model.

I am told that Confirmatory Factor Analysis (CFA) is the way to go on it.

  1. How do I perform CPA in SPSS?
  2. How do I interpret the results?

Best Answer

Short answer, I'm afraid - CFA can't be done with SPSS Base.

IBM sells the AMOS package which does Structural Equation Modelling - CFA can be done using this package. I think this costs about $600.

Your other (free) option is to use R.
