  1. Structural Equation Models with Directly Observed Variables II James G. Anderson, Ph.D. Purdue University

  2. Identification • Over Identified • Just Identified • Under Identified

  3. Covariances • Among observed variables • Among exogenous variables • Among measurement errors • Among errors in the equations

  4. Covariances among Observed Variables

  5. Covariances among Exogenous Variables

  6. Covariances among Measurement Errors

  7. Covariances among the Errors in the Equations

  8. Class Exercise • Create a new model: • From the menu choose File/New • Specify the Data file: • Choose File/Data Files • Browse to the tutorial folder. The path is: • C:\Program Files\Amos 6\Examples • In the Files of type list select SPSS • Select Fels_mal.sav • Estimate the Parameters of the different models and compare their fit statistics
