Example: apartment-prices data

With the apartments_rf we want to predict the price per square meter of an apartment and we want to explore the impact of surface and number of rooms, as they are correlated.

• The LD profiles are steeper than the PD profiles.
  • The effect of surface includes the effect of other correlated variables.
• The AL and PD profiles are parallel to each other.
  • Suggest that the model is additive for these two explanatory variables.
