Hi spssers
I ran a hierarchical regression with four IVs (two are dichotomous and two
are continuous). I am testing for interactions so I entered the 2-way
interactions at step 2 followed by three way interactions at step 3 etc.
I recently discovered from a stats professor that the beta weights are
uninterpretable because the model in SPSS does not use Type 1 sums of
squares. He has shown me how to do it in SAS. However, I would like to try
it in SPSS. Any idea how to introduce type 1 sums of squares into the
model. Thanks in advance. p.s. I am using SPSS 6.1 though have access to
later versions.
