dear colleagues,
i have the problem to do a u-test ( developed by Mann and Whitney) on
unbalanced groups. does anybody have already solved that problem and
a working sas program for it ? Or where could I look in ?
it would be possible to compute the T - and U-values by PROC RANK ; but
for small samples I could not assume a normal distribution for the
z-transformed U value. I would have to look it up in a table - uff |
On the other hand, I could offer a sas program for point-biserial
correlations using the procedure MEANS and TRANSPOSE. Is this of any use
for you ?
so long,
paul joachim elz (omp011@de0hrz1a)
