A researcher uses Gower distance for clustering a mixed dataset. Which PROC DISTANCE option computes Gower dissimilarity in SAS?
Select an answer to reveal the explanation.
Short Explanation
You need PROC DISTANCE with METHOD=DGOWER and the right NOMINAL= and INTERVAL= variable roles. That's what computes Gower's dissimilarity for mixed-type data.
Full Explanation
The correct choice is PROC DISTANCE with METHOD=DGOWER and appropriate NOMINAL= and INTERVAL= variable roles. METHOD=DGOWER computes Gower's dissimilarity coefficient for mixed-type data, with NOMINAL= for categorical and INTERVAL= for continuous variables. The PROC CLUSTER option is wrong because PROC CLUSTER consumes distance matrices from PROC DISTANCE and has no GOWER method. The PROC HPCLUS option is wrong because HPCLUS uses Euclidean distance and has no GOWER option. The PROC FASTCLUS option is wrong because FASTCLUS uses Euclidean distance.
