metric: Compute internal model metric(s)

Description

Compute internal model metric(s)

Usage

# S4 method for lcModel
metric(object, name = c("AIC", "BIC", "WRSS", "APPA"), ...)
# S4 method for list
metric(object, name, drop = TRUE)
# S4 method for lcModels
metric(object, name, drop = TRUE)

Arguments

object

The lcModel, lcModels, or list of lcModel objects to compute the metrics for.

name

The name(s) of the metric(s) to compute.

...

Additional arguments.

drop

Whether to return a numeric vector instead of a data.frame in case of a single metric.

Value

For metric(lcModel): A named numeric vector with the computed model metrics.

For metric(list): A data.frame with a metric per column.

For metric(lcModels): A data.frame with a metric per column.
