The table below shows general guidelines for choosing a statistical analysis for various survey designs.
| Design | Stata | SAS | SUDAAN | WesVar | R |
|---|---|---|---|---|---|
| Simple random sampling | Stata | SAS | SUDAAN | WesVar | R |
| Stratified with certainty PSUs | Stata | SAS | SUDAAN | WesVar | R |
| One-stage cluster sampling | Stata | SAS | SUDAAN | WesVar | R |
| Probability proportional to size sampling | Stata | SAS | SUDAAN | WesVar | R |
| Stratified random sampling | Stata | SAS | SUDAAN | WesVar | R |
| Systematic sampling | Stata | SAS | SUDAAN | WesVar | R |
| Repeated systematic sampling | Stata | SAS | SUDAAN | WesVar | R |
| Stratified random sampling with allocation to strata | Stata | SAS | SUDAAN | WesVar | R |
| Stratification after sampling (poststratification) | Stata | SAS | SUDAAN | WesVar | R |
| Other methods of estimation | |||||
| Ratio estimation | Stata | SAS | SUDAAN | WesVar | R |
| Regression estimation | Stata | SAS | SUDAAN | WesVar | R |
Note: The SUDAAN pages provide the code for SAS-callable SUDAAN, which is somewhat different from the code used in the stand-alone version of SUDAAN.
Note: The WesVar page for simple random sampling contains basic information on how to use WesVar as well as how to analyze survey data with a simple random sampling design.
