PrInDTregAll {PrInDT}

Regression tree based on all observations

Description

Regression tree based on the full sample; interpretability is checked (see 'ctestv').
The relationship between the target variable 'regname' and all other factor and numerical variables in the data frame 'datain' is modeled based on all observations.

Usage

PrInDTregAll(datain, regname, ctestv=NA, conf.level=0.95)

Arguments

datain

Input data frame with class factor variable 'classname' and the
influential variables, which need to be factors or numericals (transform logicals and character variables to factors)

regname

name of regressand variable (character)

ctestv

Vector of character strings of forbidden split results;
see function PrInDT for details.
If no restrictions exist, the default = NA is used.

conf.level

(1 - significance level) in function ctree (numerical, > 0 and <= 1);
default = 0.95

Details

Standard output can be produced by means of print(name) or just name as well as plot(name) where 'name' is the output data frame of the function.

Value

treeall

tree based on all observations

R2All

goodness of fit of 'treeall' based on all observations

interpAll

criterion of interpretability of 'treeall' (TRUE / FALSE)

Examples

data <- PrInDT::data_vowel
data <- na.omit(data)
ctestv <- 'vowel_maximum_pitch <= 320'
outreg <- PrInDTregAll(data,"target",ctestv)
outreg
plot(outreg)
