I am having some serious difficulty with getting my contrast test to run in my 2x2x2 ANCOVA. However I keep getting this error: This L matrix is not estimable. Hypothesis tests cannot be computed.


I have tried to run both a Special Contrast and a LMatrix. Could someone help me set up the syntax that I would need to test between two conditions for DV1 by A B C WITH CV1?

Thanks in advance.
