Repeated measures
General cluster-correlation
Multiply imputed analysis variables.
Unique Options for Robust Variance Estimation
SUDAAN offers eight design options to determine how standard error estimates are obtained, enabling you to specify a wide variety of sample designs often found in sample surveys and other correlated data situations. In addition, SUDAAN offers all three popular robust variance estimation methods:
Taylor series linearization (GEE for regression models)
Jackknife
Balance repeated replication (BRR).
SUDAAN is designed to handle observations that are not necessarily independent nor identically distributed.
