2 This document summarizes confirmatory factor analysis and illustrates how to estimate individual models using Amos 16.0, LISREL 8.8, Mplus 5.1, and SAS/STAT 9.1.
This document summarizes linear regression models for panel data and illustrates how to estimate each model using SAS 9.1, STATA 9.0, LIMDEP 8.0, and SPSS 13.0. This document does not address nonlinear models (i.e., logit and probit models), but focuses on linear regression models.
This document summarizes logit and probit regression models for ordinal and nominal dependent variables and illustrates how to estimate individual models using SAS 9.2, Stata 11, LIMDEP 9, and SPSS 17.
This document summarizes logit and probit regression models for binary dependent variables and illustrates how to estimate individual models using Stata 11, SAS 9.2, R 2.11, LIMDEP 9, and SPSS 18.
