Hello all, I hope this is not a repeated question.
I found that PSPP can conduct two-way anova by search, however nowhere to get how it does. I tried the Univariate analysis under Analyze menu, the result for my example dataset does not look right, the type iii ssq is 0 and results in an infinity mean square. Here is my data.
weight strain dose
106 1 1
116 1 2
145 1 3
42 2 1
68 2 2
115 2 3
70 3 1
111 3 2
133 3 3
42 4 1
63 4 2
87 4 3
I did manage to get correct result by running it without interaction term with command,
GLM weight by strain dose
/DESIGN strain dose
Can anyone tell me the usage of GLM? Any other sub-commands I can use? Thank you very much.
Best,
Shulin
