| bayes_R2 {rstantools} | R Documentation |
Generic function and default method for Bayesian version of R-squared for
regression models. See bayes_R2.stanreg in the
rstanarm package for an example of defining a method.
bayes_R2(object, ...) ## Default S3 method: bayes_R2(object, y, ...)
object |
The object to use. |
... |
Arguments passed to methods. See the methods in the rstanarm package for examples. |
y |
For the default method, a vector of y values the same length
as the number of columns in the matrix used as |
bayes_R2 methods should return a vector of length equal to the
posterior sample size.
The default method just takes object to be a matrix of y-hat values
(one column per observation, one row per posterior draw) and y to be
a vector with length equal to ncol(object).
