r_squared_poisson

Pseudo R-Squared regarding Poisson deviance

Wrapper to r_squared with deviance_function = deviance_poisson.

r_squared_poisson(actual, predicted, w = NULL, ...)

`actual`	Observed values.
`predicted`	Predicted values.
`w`	Optional case weights.
`...`	Further arguments passed to `r_squared`.

A numeric vector of length one.

r_squared(0:2, c(0.1, 1, 2), w = rep(1, 3), deviance_function = deviance_poisson)
r_squared_poisson(0:2, c(0.1, 1, 2), w = rep(1, 3))
