Interpretation tips

  • If the CP profiles are parallel and PD profile adequately summarizes them:
    • Explanatory variables are independent (not correlated)
    • There are no interactions in the model
  • By comparing PD, LD, and AL profiles may help in Identifying:
    • Whether explanatory variables are correlated (PD vs LD).
    • Whether there are any interactions in the model (PD vs AL).
  • Only the AL profile will provide a correct summary of the effect.
    • If the model is additive
    • Some explanatory variables are correlated

When there are interactions in the model, none of the profiles will provide a correct assessment: - Use a generalization of the PD profiles for two or more dependent variables.
