waterfallplot {PPtreeregViz}

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")
