Chapter 12 Local-diagnostics Plots

Introduction

If a model presents a satisfactory overall predictive performance, but it’s less accurate in some observations. Then we can say that the model does not cover well some areas of the input space.

Local-diagnostics techniques:

• Local-fidelity plots evaluate the local predictive performance of the model around the observation of interest.

• Local-stability plots assess the (local) stability of predictions around the observation of interest.
