在SAS中使用Holdout进行主成分分析并对新数据进行评分

我正在SAS企业指南中执行主成分分析，并希望计算一些坚持者的因子/成分分数

KeepCombinedLR是我真相的主要来源。我有另一个数据集，具有完全相同的变量，我希望在不将其包括在实际因素分析中的情况下对其进行评分

proc factor data = KeepCombinedLR
simple
method = prin
priors = one
rotate = varimax reorder
mineigen = 1
nfactors = 25
out = FactorScores;
var var1--var40;
run;

PROC SCORE将使用您的“坚持”数据集为您的数据打分
