Collect multiple metrics at once

A convenience function that collects all given metrics at once. This can save time compared to manually calling all metric functions individually, as some variables can be reused instead of being calculated multiple times.

Usage

metric_list_handler(fit, metrics, data_gen_output, fit_conf, ...)

Arguments

fit

A brmsfit object.

metrics

A vector of metric identifiers. See details for supported identifiers.

Value

A named list containing all requested metrics' results.
