我很想知道,通过每一方面进行交叉验证的最佳方法是什么。 例如,我要把第1条作为我的测试组,第2、3、4、5条作为培训组,第2条将第2条用作测试,第1、3、4、5条用作培训等。

Thanks!

Probably best to call upon a macro to make it a bit easier to call upon.
%Macro Validate(cur,i) ;
%Do j = 1 %to 5 ;
%If &j <> &i %THEN
%DO;
Data &Cur._&j. ;
Set &cur S&j. ;
<validation steps>
Run;
%END;
%End;
%mend Validate ;
Data _null_ ;
Do i = 1 to 5 ;
Call Execute("%Validate(s"||strip(i)||","||strip(i)||");");
End;
Run;
Proc gmlselect performs k-folds cross validation with multiple methods to choose best models. It is experimental in 9.1 but released in production for 9.2+
