Hi,
I am trying to run a between group analysis in QDEC whilst controlling for intrancranial volume. The design has one dichotomous variable (group2, group2), one continuous (performance on behavioral task), and one nuisance variable (intracranial volume). each time I run it qec crashes with the following error:
MatrixMultiply: ml null!What does this error mean and how can I fix it?
What is odd is that this error does not seem to be consistently reproducible - after successfully running the analyses without controlling for ICV, I was then able to run it with ICV as a nuisance factor.
Thank you!
Laura.
