Chapter 18 Local-dependence and Accumulated-local Profiles

Learning objectives:

• Understand the limitations of Partial-dependence (PD) profiles when dealing with correlated dependent variables.
• Grasp the concept of Local-dependence (LD) profiles and their ability to address the shortcomings of PD profiles in specific scenarios.
• Be familiar with Accumulated-local (AL) profiles and their role in summarizing the effect of a variable while averaging out the effects of other variables in additive models.
• Learn how to identify interactions between explanatory variables by comparing PD, LD, and AL profiles.
• Gain insights into interpreting the profiles and drawing conclusions about the relationships between variables in a model.
• Be introduced to the DALEX package as a tool for calculating these profiles and the model_profile function for different profile types.
