Problem 1: Find the best model you can for these data using your everyday understanding of the variables as a guide. To achieve this aim specify a CFA and an SEM model for the data below using CALIS. These variables can be used to represent relationships among poverty, alcohol use, alcohol-related problems and alcohol dependence using the following variables (use your common sense and imagination). You may specify your own model with any subset of the variables below. Then, please summarize your results by addressing, in particular, 1. Provide a copy of both models generated by SAS (the diagram with fit indices). 2. Comment on Fit Index results for each (RNISEA, SRNIR, CFI) 3. Comment on results for individual estimates for each model (were any of them not statistically significant?).
