In FlexReg: Regression Models for Bounded Responses

Description

Bayesian version of R-squared for flexible regression models for continuous bounded or binomial data.

Usage

R2_bayes(model)

Arguments

model

an object of class `flexreg`, usually the result of flexreg or flexreg_binom.

Details

The function provides a Bayesian version of the R-squared measure, defined as the variance of the predicted values divided by itself plus the expected variance of the errors.
