surveygenmod2: A SAS macro for estimating complex survey adjusted generalized linear models and Wald-type tests

TL;DR

surveygenmod2 is an updated SAS macro that facilitates estimation of generalized linear models with complex survey data and enables Wald-type hypothesis testing on model parameters.

Contribution

It introduces new features for Wald-type tests and fixes bugs in the previous version of the macro for better survey data analysis in SAS.

Findings

Enhanced macro with bug fixes and new testing features

Improved accuracy in complex survey GLM estimation

Supports hypothesis testing on model parameters

Abstract

surveygenmod2 builds on the macro written by da Silva (2017) for generalized linear models under complex survey designs. The updated macro fixed several minor bugs we encountered while updating the macro for use in SAS\textregistered. We added additional features for conducting basic Wald-type tests on groups of parameters based on the estimated regression coefficients and parameter variance-covariance matrix.
