Hi,
I’m running an analysis in Qdec in which I’d like to control for 3 variables (1 discrete (sex), 2 continuous (age and IQ)).
In the output after I run the model: I only see a reference to an effect of my factor of interest controlling for sex (i.e., there is no contrast that also explicitly says controlling for sex, age, and IQ).
Is this implied? Or are age and IQ not controlled for here? Is there a way to specify that I’d like to look for an effect controlling for all 3 variables?
