Why is PROC SURVEYLOGISTIC preferred over PROC LOGISTIC for survey data analysis?
Select an answer to reveal the explanation.
Short Explanation and Infographic
Here's the deal — c is correct because complex surveys use stratified, clustered, weighted sampling. Ignoring design features with standard PROC LOGISTIC underestimates standard errors because clustered observations are correlated.

Full Explanation
C is correct because complex surveys use stratified, clustered, weighted sampling. Ignoring design features with standard PROC LOGISTIC underestimates standard errors because clustered observations are correlated. PROC SURVEYLOGISTIC explicitly models sampling design for valid variance estimates. A is wrong; missing data handling is not the distinction. B is wrong; both procedures produce confidence intervals. D is wrong; CAS integration is not the differentiating feature.
