DIFFERENCE OF TRIMMED MEANName:
For the differeence of trimmed means, the trimmed mean 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 trimmed means is stored; and where the <SUBSET/EXCEPT/FOR qualification> is optional.
