The SS for B are what you would get from a one-way ANOVA with only B as a
factor. I would expect it to be Seq SS (from packages that reoprt such a thing
when B is the first effect in the model).
In fact, you *didn't* run ANOVA through SYSTAT. If you had run
cat a b
anova y
es
it would have failed due to the empty cell (2,2). What exactly did you do?
I would guess
model y=constant + a + b
To replicate Statistica's analysis in SYSTAT, use
cat a b
model y = a*b/means
