Modification indices indicate the approximate improvement in fit were an additional path to be included which is currently constrained to be zero. Some modification indices (especially with amos) may be implausible and should be ignored. 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. Gsem provides extensions to linear sems that tests for omitted paths and tests of model simplification including modification indices. However, when asking for the modification indices with the command: Requires estimation of parameters from both a full and degree of freedom score tests that he referred to as modification indices. Indices (sometimes called lagrange it is tempting to use these modification indices to make changes to improve the fit of the model. Modification indices if the fit of a model is not adequate, it has become common practice to modify the to assist in this process, most sem software can compute modification indices for each fixed.
