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: **

It's in the chapter "Introduction to Statistical Modeling with SAS/STAT Software" in the section "Type III and IV SS and Estimable Functions"
