R2_bayes {FlexReg} | R Documentation |
Bayesian R-squared for flexreg
Objects
Description
Bayesian version of R-squared for flexible regression models for bounded continuous and discrete responses.
Usage
R2_bayes(model)
Arguments
model |
an object (or a list of objects) of class |
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.
Value
A list with the same length as the number of objects of class `flexreg`
passed in the model
argument.
Each element of the list contains a vector of Bayesian R-squared values with the same length as the Markov Chain(s) after warmup.
