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
