    Question

    Single regression shows that the amount of antidepressants administered is predictive of depression severity after 1 month of use. However, if a multiple regression statistically controls for severity of depression at the start of antidepressant use, the relationship between antidepressant use and severity of depression after 1 month of use disappears. What type of multivariate relationship are we dealing with here?


    1. TRUE: Spurious relationship.
    2. FALSE: Interaction effect.
    3. FALSE: Simpson’s paradox.
    4. FALSE: Suppressor effect.
