- Do you mean to say that SPSS does not read your mind
in order to determine that you have 3 categories,
when you neither told it the range -- CHISQUARE=varx(1,3), say --
nor told it that there were *three* categories by specifying
or do you mean to say that SPSS
actually has an oversight in the programming for NONPAR ?
(And, if so, could you be specific?)
