sas test statement

[smorkoc]

Hi,

I'm having a problem with the result of test statement. Actually here is my code, but in glm section, Idk what the problem is but i see bunch of dots.. 

proc glm data=ndata.butner_total_respiration_new ;
class block Spacing tno;
model log_CO2flux =block spacing tno spacing*tno block*spacing*tno ;

test h=block e=block*spacing*tno/ etype=3;

test h=spacing e=block*spacing*tno/ etype=3;

test h=tno e=block*spacing*tno/ etype=3;

test h=spacing*tno e=block*spacing*tno/ etype=3;



run;
ods graphics off;

Your error sum of squares is zero. Meaning that all available degrees of freedom are taken by your model parameters. This is not a problem if your intent was to test the parameters with other error terms, as you did with your test statements.

So, should my class statement include all the variables seen in error terms?

All the terms mentioned in your test statements must appear in your model and all model categorical variables must be mentioned in the class statement.
