a question on df of linear model
Dear R-users:
On page 155 of "Mixed-effects Models in S and S-Plus", the degree of
freedoms of the anova comparison of lme and lm are 8 and 5.
But when I use the following SAS code:
proc glm data=ortho2;
class gender;
model distance = age|gender / solution ;
run;
The df is 3.
Could you please explain this to me?
Thanks
Joe
