Hi there...quick question....in the old MANOVA procedure when testing for a two-way interaction (for a general factorial design), both partial eta squared and eta squared were included in the ouput.......however, in UNIANOVA (SPSS 8.0) only the eta squared is reported, even though technically it is the partial eta squared, as calculations will show that the sum of squares of the other effects are partialed out.........so is there a way (outside of doing the obvious hand calculations: i.e., (sum of squares/corrected model sum of squares) for each of the main effects/interaction terms, that I can derive the eta squared like the old MANOVA procedure?

thank you..................dale glaser
