Bruce, those should only change the standard error of the means, not the mean
estimate itself (at least that is the case for data with only discrete dummy
variables like here).

Here I am not sure how SPSS treats the random effect in EMMEANS (sets it to
0 I imagine). If you don't estimate random effects the two procedures match.

MEANS CHOICE BY AC BY WT.

GENLINMIXED /DATA_STRUCTURE SUBJECTS=SUB
 /FIELDS TARGET=CHOICE TRIALS=NONE OFFSET=NONE
 /TARGET_OPTIONS DISTRIBUTION=BINOMIAL LINK=LOGIT REFERENCE=0
 /FIXED EFFECTS= AC WT AC*WT USE_INTERCEPT=TRUE
 /EMMEANS TABLES=AC*WT
 /BUILD_OPTIONS TARGET_CATEGORY_ORDER=aSCENDING
INPUTS_CATEGORY_ORDER=aSCENDING.
