About SUDAAN
SUDAAN is a statistical software package for analyzing correlated and complex survey data.
SUDAAN is a specialized statistical software package from RTI International, a non-profit research institute. It is engineered specifically for the analysis of complex survey data and other correlated data, such as from clustered or longitudinal studies. The software provides a suite of procedures that correctly account for complex sample designs (e.g., stratification, clustering, unequal weighting) to produce accurate statistical inferences and variance estimates. Key capabilities include descriptive statistics, cross-tabulations, linear and logistic regression, and survival analysis, all adapted for survey data. It also offers advanced tools for weight adjustment and multiple imputation. SUDAAN is aimed at statisticians, epidemiologists, social scientists, and researchers who require rigorous methods for analyzing data from large-scale surveys and studies. Pricing is not publicly available, and support is offered via email and phone. The software is a standalone application for Windows.
Pros & Cons
- Specifically designed to handle complex survey data, accounting for clustering, stratification, and weighting.
- Offers a wide range of statistical procedures, from descriptive statistics to advanced modeling.
- Developed and supported by experts at RTI International, a major research institute.
- Provides robust methods for variance estimation, including Taylor series and replication methods.
- Includes tools for data preparation, such as weight adjustment and multiple imputation.
- Pricing information is not publicly available and requires contacting the vendor.
- Has a steep learning curve, particularly for those not familiar with survey statistics.
- Lacks a free trial or free tier for evaluation purposes.
- The user interface may be less modern compared to other mainstream statistical packages.
Features
Key features
Accounts for stratification, clustering, and unequal weighting in survey data to produce accurate variance estimates.
Computes frequencies, percentage distributions, odds ratios, relative risks, and chi-square tests for cross-tabulations.
Supports linear regression, logistic regression (binary, multinomial, ordinal), and survival models (proportional hazards).
Provides tools for nonresponse and poststratification sample weight adjustments, and multiple imputation for item nonresponse.
Implements Taylor series linearization and replication methods (BRR, Jackknife) for variance estimation.
Additional features
Computes estimates, standard errors, and confidence limits for generalized ratios.
Allows for testing single-degree-of-freedom contrasts among levels of a categorical variable.
Performs chi-square tests associated with stratified two-way tables.
Includes procedures for analyzing survival data, such as proportional hazards models.
Computes point estimates and variances for user-defined parameters expressed as functions of means, totals, or ratios.
Provides a test for homogeneity of odds ratios or relative risks.
Calculates Kappa statistics for inter-rater reliability.
Computes standardized estimates for ratio and descriptive procedures.
