Bagged Earth

A bagging wrapper for multivariate adaptive regression splines (MARS) via the earth function

Keywords
regression
Usage
## S3 method for class 'formula':
bagEarth(formula, data = NULL, B = 50,
         summary = mean, keepX = TRUE,
         ..., subset, weights, na.action = na.omit) 
## S3 method for class 'default':
bagEarth(x, y, weights = NULL, B = 50, 
         summary = mean, keepX = TRUE, ...)
Details

The function computes a Earth model for each bootstap sample.

Value

  • A list with elements
  • fita list of B Earth fits
  • Bthe number of bootstrap samples
  • callthe function call
  • xeither NULL or the value of x, depending on the value of keepX
  • ooba matrix of performance estimates for each bootstrap sample
