bagEarth: Bagged Earth

Description

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

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, ...)

Value

• A list with elements
• fit
  a list of B Earth fits
• B
  the number of bootstrap samples
• call
  the function call
• x
  either NULL or the value of x, depending on the value of keepX
• oob
  a matrix of performance estimates for each bootstrap sample

Details

The function computes a Earth model for each bootstap sample.
