Description Usage Arguments Value Examples

This function selects the `carx`

model which minimizes the AIC among a set of `carx`

models
defined by a set of formulas or a list of regression formulas with a maximal AR order.
The model specification is supplied by `formulas`

which can be either a formula or a list of formulas.
For each formula, the function will estimate the `carx`

models with the AR order
from 1 to `max.ar`

inclusive.
If `detect.outlier=TRUE`

, outlier detection will be performed for each combination of model
formula and AR order.
The function returns a `list`

which consists of: 1) `aicMat`

which is a matrix of AIC
values where
each row contains the AICs of the model given by a specific regression formula with the AR order
ranging from 1 to `mar.ar`

(after incorporation of any found outlier if outlier detection if enabled), and
2) `fitted`

which is the fitted object of the selected model.

a `carx`

object with an additional element `selectionInfo`

which is a list consisting of the information about the selection, in particular,
`aicMat`

, the matrix of AIC where rows correspond to the model formulas and columns correspond to the AR orders.
