DIFFERENCE OF WINSORIZED VARIANCEName:
For the difference of Winsorized variances, the Winsorized variance is computed for each of two samples then their difference is taken.
<SUBSET/EXCEPT/FOR qualification> where <y1> is the first response variable; <y2> is the first response variable; <par> is a parameter where the computed difference of the Winsorized variance is stored; and where the <SUBSET/EXCEPT/FOR qualification> is optional.
