Waterfall plot

Description

waterfall plot for PPKernelSHAP

Usage

waterfallplot(
  PPTreeregOBJ,
  testObs,
  final.rule = 5,
  method = "simple",
  final.leaf = NULL
)

Arguments

PPTreeregOBJ	PPTreereg class object - a model to be explained
testObs	test data observation
final.rule	final rule to assign numerical values in the final nodes. 1: mean value in the final nodes 2: median value in the final nodes 3: using optimal projection 4: using all independent variables 5: using several significant independent variables
method	simple or empirical method to calculate PPKernelSHAP
final.leaf	location of final leaf

Details

Waterfall plot is mainly used to explain individual predictions, and is suitable for showing an explanation when a single piece of data is entered as an input using PPKernelSHAP values.

Value

An object of the class ggplot

Examples

data(dataXY)
testX <- dataXY[1,-1]
Model <- PPTreereg(Y~., data = dataXY, DEPTH = 2)
waterfallplot(Model, testX, final.rule =5, method="simple")
