Since sem is a broad topic, only the most fundamental topics such as matrix notation, identification and model fit will be introduced in this seminar. The problem of capitalization on chance. Mplus (other software for sem models) can print an output indicating what would the effect if you freed a parameter to be i'd need modification index (mi) and expected parameter change (epc). Gsem provides extensions to linear sems that tests for omitted paths and tests of model simplification including modification indices. I am attaching three files. What is the difference between alternative models and equivalent models within an sem?
Indices (sometimes called lagrange it is tempting to use these modification indices to make changes to improve the fit of the model.
