##### 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
fit a list of `B`

Earth fitsB 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
