chantrics adjusts the loglikelihood of common econometric models for
clustered data based on the estimation process suggested in
Chandler and Bate (2007),
using the chandwich package,
and provides convenience functions for inference on the adjusted models.
adj_loglik() adjusts the model's parameter covariance matrix to
incorporate clustered data, and can mitigate model misspecification by
chandwich::adjust_loglik for the supported models.
The returned model of class
chantrics can be plugged into standard model
evaluation and model comparison methods, for example,
anova(), and a hypothesis test framework provided by
vignette("chantrics-vignette", package = "chantrics") for an
overview of the package.
