log_lik: Generic function for pointwise log-likelihood

Description Usage Arguments Value See Also Examples

View source: R/log_lik.R

Description

We define a new function log_lik rather than a logLik method because (in addition to the conceptual difference) the documentation for logLik states that the return value will be a single number, whereas log_lik returns a matrix. See log_lik.stanreg in the rstanarm package for an example.

Usage

1
log_lik(object, ...)

Arguments

object

The object to use.

...

Arguments passed to methods. See the methods in the rstanarm package for examples.

Value

log_lik methods should return a S by N matrix, where S is the size of the posterior sample (the number of draws from the posterior distribution) and N is the number of data points.
