Plot partial dependencies for a variable across multiple models
Plot partial dependencies for a variable across multiple models
Partial dependence plot (PDP) gives a graphical depiction of the marginal effect of a variable on the response. The effect of a variable is measured in change in the mean response. PDP assumes independence between the feature for which is the PDP computed and the rest.
max_levels: An integer specifying the maximum number of factor levels to show. Defaults to 30.
show_rug: Show rug to visualize the density of the column. Defaults to TRUE.
Returns
A ggplot2 object
