Subject: syntax for contrasts
Content-Type: text/plain; charset="windows-1255"
My design is quite simple two independent variables A and B each with two levels(1 or 2).I performed ANOVA
y BY a b
/METHOD = SSTYPE(3)
/INTERCEPT = INCLUDE
/PRINT = DESCRIPTIVE
/CRITERIA = ALPHA(.05)
/DESIGN =a b a*b .
The interaction is significant and I want to test the simple effects of B.
That is, to perform two contrasts the first between the two levels of B for A=1 and the second between the two levels of B for A=2.
What is the syntax that I should use for this contrast?
I will appreciate any help
