mtry.guide: Recommended mtry range

In SarahAsbury/BioDataTools:

Recommended mtry range

Description

Recommended mtry range based on number of paramerets and tree type

Usage

mtry.guide(npred, rf.type, spread.upper = 5, spread.lower = 4)

Arguments

npred	Numeric. Input number of predictor variables.
rf.type	One of: "class" for classification trees or "reg" for regression trees.
spread.upper	Upper range of mtry to use above optimal mtry value, Default: 5
spread.lower	Lower range of mtry to use below optimal mtry value: 4

Details

Written primarily for rf wrapper function

Value

Returns a list:
ideal.mtry is optimal mtry based on tree type and number of predictor variables
upper.mtry is upper range of mtry for downstream hyperparameter tuning
lower.mtry is lowest value of mtry for downstream hyperparameter tuning
range is range of mtry values to try in downstream hyperparameter tuning given in the format: upper.mtry:lower.mtry
