fixest (version 0.7.0)

BIC.fixest: Bayesian information criterion

Description

This function computes the BIC (Bayesian information criterion) from a fixest estimation.

Usage

# S3 method for fixest
BIC(object, ...)

Arguments

object

A fixest object. Obtained using the functions femlm, feols or feglm.

...

Optionally, more fitted objects.

Value

It return a numeric vector, with length the same as the number of objects taken as arguments.

Details

The BIC is computed as follows: $$BIC=-2\times LogLikelihood+\log (nobs)\times nbParams$$ with k the penalty parameter.

You can have more information on this criterion on AIC.

Examples

# NOT RUN {
# two fitted models with different expl. variables:
res1 = femlm(Sepal.Length ~ Sepal.Width + Petal.Length +
            Petal.Width | Species, iris)
res2 = femlm(Sepal.Length ~ Petal.Width | Species, iris)

AIC(res1, res2)
BIC(res1, res2)
