Exploratory Factor Analysis with SAS

Example Syntax and Output

Theory. The first criterion summarized above is unfortunately not something that SAS can help you with. This requires combing the literature to better understand the theoretical constructs that might underlie your set of items. The literature might identify one specific structure (e.g., a two-factor model) or multiple structures (e.g., a two-factor model under one framework and a five-factor model under another). It is your job to understand these models and then test them with your data.

If we think back to the engineering data that we used in Chapter 2, the scale used was designed to evaluate two factors: engineering problem-solving and interest in engineering. We could do some additional research to see whether ...
