SUDAAN is designed to handle observations that are not necessarily independent nor identically distributed.
nternationally recognized statistical software package for analyzing data from complex studies
Developed by our expert statisticians and programmers, SUDAAN is a software package designed for researchers who work with study data. SUDAAN procedures properly account for correlated observations, clustering, weighting, stratification, and other complex design features—making them ideal for efficiently and accurately analyzing data from surveys and experimental studies.
Unequally weighted or unweighted data
Stratification
With- or without-replacement designs
Multistage and cluster designs
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.
By adding SUDAAN to your suite of statistical analysis tools, you will be able to perform more complex statistical procedures such as weight calibration and imputation, and support a wider range of survey designs with our fully tested and proven solution.
