A data scientist runs PROC PRINCOMP and uses the OUTSTAT= option. What information does the OUTSTAT= dataset contain?
Select an answer to reveal the explanation.
Short Explanation and Infographic
Here's the deal — b is correct because PROC PRINCOMP's OUTSTAT= dataset contains the statistical information needed to score new data: eigenvectors (loadings), eigenvalues, means, and standard deviations. This is distinct from the OUT= option which produces a dataset with principal component scores for the analysis observations.

Full Explanation
B is correct because PROC PRINCOMP's OUTSTAT= dataset contains the statistical information needed to score new data: eigenvectors (loadings), eigenvalues, means, and standard deviations. This is distinct from the OUT= option which produces a dataset with principal component scores for the analysis observations. A describes OUT=. C is reported in the printed output, not specifically OUTSTAT=. D describes variable importance ranking, not OUTSTAT=.
