mlr_learners_regr.rsm: Regression Response Surface Model Learner

In mlr-org/mlr3extralearners: Extra Learners For mlr3

Regression Response Surface Model Learner

Description

Fit a linear model with a response-surface component. Calls rsm::rsm() from rsm.

Custom mlr3 parameters

• modelfun: This parameter controls how the formula for rsm::rsm() is created. Possible values are:

  • "FO" - first order

  • "TWI" - wo-way interactions, this is with 1st oder terms

  • "SO" - full second order

Dictionary

This Learner can be instantiated via the dictionary mlr_learners or with the associated sugar function lrn():

mlr_learners$get("regr.rsm")
lrn("regr.rsm")
