predict.PPTreereg {PPtreeregViz}

predict PPTreereg

Description

predict projection pursuit regression tree

Usage

## S3 method for class 'PPTreereg'
predict(
  object,
  newdata = NULL,
  Rule = 1,
  final.rule = 1,
  classinfo = FALSE,
  ...
)

Arguments

object

a fitted object of class inheriting from PPTreereg

newdata

the test data set

Rule

split rule 1: mean of two group means 2: weighted mean of two group means - weight with group size 3: weighted mean of two group means - weight with group sd 4: weighted mean of two group means - weight with group se 5: mean of two group medians 6: weighted mean of two group medians - weight with group size 7: weighted mean of two group median - weight with group IQR 8: weighted mean of two group median - weight with group IQR and group size 9: cutoff that minimize error rates in each node

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

classinfo

return final node information. Default value is FALSE
