basically just know what the formulas are in it, and then do the algebra. For example, if they ask you what MSSr is, and show you an ANOVA table without it, but it has some other stuff, you just compute
SSE/(n-k-1)
and that's your answer.
if it asks you what the adjusted R2 is, and you see only the ANOVA table, you do
regular R2 = RSS/TSS or 1 - SSE/TSS
then you do adj R2 = 1 - [(n-1)/(n-k-1)](1 - R2)
and circle the right one.
and so on |
