Re: ANOVA table not in the .ASR file.

Dear Dr. Gilmour,

Thanks for your reply. Actually the levels of GROUP2 are nested within
the levels of GROUP1. Also, the way the data is constructed is that the
unique combination of GROUP1 and GROUP2, (let's call it as entry) was
used in the model instead of the actual levels of GROUP2. What I mean by
that is if there are 3 levels of GROUP1, with the following levels of
GROUP2 nested within GROUP1,

GROUP1 GROUP2 ENTRY
1 1 1
1 2 2
1 3 3
2 1 4
2 2 5
2 3 6
2 4 7
3 1 8
3 2 9
3 3 10
3 4 11
3 5 12

The model that did not produce ANOVA table was

tabulate RESPONSE ~ GROUP1 GROUP2
 RESPONSE ~ mu GROUP1/ENTRY !r REP REP.GROUP1
 predict GROUP1 !PRESENT GROUP1 ENTRY!SED !TDIFF
 predict GROUP1.ENTRY !SED !TDIFF

You are correct in that for the above model, the solutions for GROUP1
effects were all 0.

If I use the following model then everything is fine and all the outputs
are produced.

tabulate RESPONSE ~ GROUP1 GROUP2
 RESPONSE ~ mu GROUP1/GROUP2 !r REP REP.GROUP1
 predict GROUP1 !PRESENT GROUP1 GROUP2!SED !TDIFF
 predict GROUP1.ENTRY !SED !TDIFF

Dear Subhash,

I am surprised the ANOVA table is completely missing for the model you
propose. If the levels of GROUP1 were nested in the levels of GROUP2
(nested within mu), then fitting GROUP1 (ahead of GROUP2) would sweep
out
the GROUP2 DF and so the line in the ANOVA for GROUP2 will be missing.
You can look in the .sln file and see all the GROUP2 effects are zero,
and there is more ANOVA information in the .aov file which shpuld make
it
clearer what will happen.

The only reason all terms would disappear from the ANOVA table is if
there is a fixed effect fitted as SPARSE which sweeps out all the DF.

Consider sites nested within localities

  S1 and S2 in L1
  S3 S4 S5 in L2

 res ~ mu Loc Site !r Rep.Site

should produce ANOVA

mu 1
Loc 1
Site 3

but

 res ~ mu Site Loc !r Rep.Site

should produce ANOVA

mu 1
Site 4

and

 res ~ mu Loc !r Rep.Site !f Site

should produce no lines in the ANOVA table
because all 5 DF are swept out in the SPARSE section.

The table heading should be present though.

I trust this helps

If you really do have a job woth NO ANOVA table, but which finished
properly, I need to see it.
