additivityLineup: Lineup plot for additivity

In ICEbox: Individual Conditional Expectation Plot Toolbox

Lineup plot for additivity

Description

This function creates a lineup plot to assess the additivity of a predictor's effect. It uses a nonparametric bootstrap approach to generate null plots.

Usage

additivityLineup(
  backfit_obj,
  fitMethod,
  realICE,
  figs = 10,
  colorvecfcn,
  usecolorvecfcn_inreal = FALSE,
  null_predictfcn,
  ...
)

Arguments

backfit_obj	An object of class backfitter.
fitMethod	A function that accepts X and y and returns a fitted model.
realICE	The ice object for the real data.
figs	The total number of plots in the lineup (including the real one). Default is 10.
colorvecfcn	Optional function to generate a color vector for the curves.
usecolorvecfcn_inreal	If TRUE, use colorvecfcn for the real plot.
null_predictfcn	Optional prediction function for the null models.
...	Additional arguments passed to plot.ice.

Value

An object of class additivityLineup (invisibly).
