chase: Chases a 'Sdt' value

In fftrees: Fast- and Frugal Tree Analysis

Description

Takes all cues in fftree and builds a fftree from scratch, by appending the 'next best' or prepending the 'previous best' cue according to given parameters. You can chase multiple parameters by specifying an array of whatToMaximize and chaseHow like this: whatToMaximize = c("dPr","percCorrect","crit"), chaseHow=c("max","max","min")) and forward=c(TRUE,TRUE,FALSE)). Use Fftm instead of calling this method directly.

Usage

fftm.chase(tree, whatToMaximize, chaseHow = "max", forward = TRUE)

Arguments

tree	fftree
whatToMaximize	stringvector; Which parameters of the tree should be chased? The index of the vector represents the sequence. See Sdt for possible values.
chaseHow	stringvector; Every item has to be either max or min.
forward	OPTIONAL logicalvector: Should the next test be appended or prepended to the current tree? Default is forward = TRUE

Details

You can chase all values of Sdt and getCueEfficiency

Value

Fftree

Examples

rawdata <- fftm.Titanic.data()
tree <- Fftm(Survived ~ Age, "chase",rawdata, whatToMaximize = "percCorr", chaseHow = "max", forward=TRUE)
tree2 <- Fftm(Survived ~ Age, "chase",rawdata, whatToMaximize = c("percCorr","dPr"), chaseHow = c("max","min"), forward=c(TRUE,FALSE))
