MIXED has an EMMEANS sub-command.  You can use it to generate fitted values of Y at various combinations of the explanatory variables.  Will that give you what you're after?  Here's an example for a much simpler model from the fine manual.

MIXED Y BY A B WITH X
 /FIXED A B X
 /EMMEANS TABLES(A*B) WITH(X=0.23) COMPARE(A) ADJ(SIDAK)
 /EMMEANS TABLES(A*B) WITH(X=MEAN) COMPARE(A) REFCAT(LAST) ADJ(LSD).

MIXED also has a TEST sub-command, which can be used for crafting any comparisons you wish to make.  See several posts to this list by Ryan for nice examples of how to use it.

HTH.

Dear subscribers,

I would like to get the parameter estimation on ALL the categories (time 1, time 2, time 3) in my three-way interaction analysis. As of now, SPSS only estimates time 1 and 2 (as it often does with categorical data).

How may I obtain this information? Please find present syntax below:

mixed Exlog with OPce Posce pssce pcsce Gender Age Sector Respons Tenure Hour_w BY time
/CRITERIA=MXITER (5000)
/print=solution
  /method=reml
  /fixed = Gender Age Sector Respons Tenure Hour_w OPce time OPce*time OPce*POSce OPce*PsSce OPce*PcSce PoSce pssce pcsce pssce*time pcsce*time Posce*time POSce*OPce*time PsSce*OPce*time PcSce*OPce*time
  /random intercept time | subject(id) covtype(VC).

Best regards,
Kine
