Subject:      simple main effects

Hi SPSSERS

I have a mixed factorial design and have a three-way interaction (delivery
x dichmast x organize). I want to do followup comparisons using the simple
effects procedure looking at delivery x organize at each level of dichmast.
Dave Nichols's paper on simple main effects is very useful, but I am unsure
on the syntax to use when I have a covariate and a repeated measures
design. Thanks in advance. Here is my syntax for the overall design:


MANOVA
  totpro_1  totpro_2  BY delivery(1 2) dichmast(1 2) organize(1 2)
WITH(totper_1)
  /WSFACTORS time(2)
  /METHOD UNIQUE
  /ERROR WITHIN+RESIDUAL
  /POWER T(.05) F(.05)
  /PRINT SIGNIF( MULT AVERF EFSIZE  )cellinfo (means)
  /NOPRINT PARAM(ESTIM) .
