Marginal Model Plots (LOESS/ LOWESS Calculation Method)

This add-in produces marginal model plots. Marginal model plots are used to assess the fit of a given model.

These are philosophically similar to the Marginal Model Plots produced under the Variable Importance outline in the Profiler, but they are calculated differently (based on the LOESS methodology), whereas those under Variable Importance are computed using a sobol-based decomposition method.

 

For more information about the LOESS methodology, consider the following references:
