Dear Douglas, 

Thank you for your reply. Does this mean that if I were to have a continuous variable (i.e. Neuroinflammation) and a categorical variable with 2 levels (i.e. gene positive and gene negative), interaction can also be found using QDEC? 

Thank you. 

Best Regards, 
Heidi Foo

This is done automatically when you have two categorical variables and
two continuous variables. This is equivalent to asking whether the two
slopes differ across the two categorical variables.
