residuals.bootstrap.mat: Extract Bootstrapped Model Residuals

Description

residuals is a generic function which extracts model residuals from objects returned by modeling functions. residuals.bootstrap.mat is a residuals method for mat models.

The abbreviated form of this function is resid.

Usage

## S3 method for class 'bootstrap.mat':
residuals(object, which = c("model", "bootstrap"), ...)

Arguments

object

an object of class bootstrap.mat.

which

character; which set of residuals to return, the model residuals or the residuals of the bootstrap-derived estimates?

...

arguments pass to or from other methods.

Value

• A list containg the requested residuals and metadata, with the following components:
• model
  Leave one out residuals for the MAT-estimated model.
• bootstrap
  residuals for the bootstrapped MAT model.
• k
  numeric; indicating the size of model used in estimates and predictions.
• n.boot
  numeric; the number of bootstrap samples taken.
• auto
  logical; whether "k" was choosen automatically or user-selected.
• weighted
  logical; whether the weighted mean was used instead of the mean of the environment for k-closest analogues.

Details

Typical usages are resid(object, which = c("model", "bootstrap"), \dots)

## fit the MAT model using the squared chord distance measure
swap.mat <- mat(swapdiat, swappH, method = "SQchord")

## bootstrap training set
swap.boot <- bootstrap(swap.mat, k = 10, n.boot = 100)
