AIC.lcc: Akaike and Bayesian Information Criteria for an 'lcc' Object

In Prof-ThiagoOliveira/lcc: Longitudinal Concordance Correlation

Akaike and Bayesian Information Criteria for an lcc Object

Description

Calculates the Akaike Information Criterion (AIC) or the Bayesian Information Criterion (BIC) for a fitted longitudinal concordance correlation model represented by an lcc object.

Calculates the Bayesian Information Criterion (BIC) for a fitted longitudinal concordance correlation model represented by an lcc object. BIC is used for model selection, with lower values indicating a better model.

Usage

## S3 method for class 'lcc'
AIC(object, ..., k = 2)

## S3 method for class 'lcc'
BIC(object, ...)

Arguments

object	An object of class lcc, representing a fitted longitudinal concordance correlation function.
...	Optional arguments passed to the underlying BIC function from the stats package.
k	Numeric value used as a penalty coefficient for the number of parameters in the fitted model; the default k = 2 corresponds to the classical AIC.

Details

The function computes AIC or BIC values as a measure of the relative quality of statistical models for a given set of data. Lower AIC or BIC values indicate a better model fit with fewer parameters. For more information, refer to the methods for AIC objects.

The function computes BIC as a measure of the trade-off between model fit and complexity. It is particularly useful for comparing models with different numbers of parameters. For more information, refer to the documentation for BIC.
