Using SAS for Qualitative and Limited Dependent Variables LSU Economics Department May 4, 2012
Limited DepVar: PROC QLIM • linear regression model with heteroskedasticity • Box-Cox regression with heteroskedasticity • probit with heteroskedasticity • logit with heterokcedasticity • tobit (censored and truncated) with heteroskedasticity • bivariate probit • bivariate tobit • sample selection and switching regression models • multivariate limited dependent variables • stochastic frontier production and cost models
Multinomial Choice: PROC MDC • Conditional Logit: Estimation and Prediction • Nested Logit Modeling • Multivariate Normal Utility Function • HEV and Multinomial Probit: Heteroscedastic Utility Function • Parameter Heterogeneity: Mixed Logit
Count Data: PROC COUNTREG • Poisson regression • negative binomial regression with quadratic (NEGBIN2) and linear (NEGBIN1) variance functions (Cameron and Trivedi 1986) • zero-inflated Poisson (ZIP) model (Lambert 1992) • zero-inflated negative binomial (ZINB) model
