SURVEYLOGISTIC Procedure


9.1  

The SURVEYLOGISTIC procedure performs logistic regression on data that arise from a survey sampling scheme. PROC SURVEYLOGISTIC incorporates complex survey sample designs, including designs with stratification, clustering, and unequal weighting , in its estimation process. Variances of the regression parameters and odds ratios are computed using a Taylor expansion approximation . The SURVEYLOGISTIC procedure is similar in syntax to the LOGISTIC procedure, and it can fit link functions such as the logit, cumulative logit, generalized logit, probit, and complementary log-log functions. Maximum likelihood estimation of the regression coefficients is carried out with either the Fisher-scoring algorithm or the Newton-Raphson algorithm.
