Hi, 

 

I was looking for the equations used to calculate the Type III sum of squares obtained from the following code, but I could not find it. I only found the formula for Type I sum of squares, but I need the Type 3 SS. Can anyone lead me to where I can get the Type 3 SS equations, i.e., SS(A),SS(B),SS(A*B),SSE? I apologize that this is not really a SAS question. I appreciate your help. Thanks!

 

Here is the SAS code: 

data try;
input y batch $ time;
DATALINES;
10 A 1
10 A 2
30 A 3
10 B 1
20 B 2
10 B 3
;
run;


proc glm;
class batch;
model y=batch|time/ solution;
run;

 

Here is the SAS output for Type 3 SS:
