Tidy a zeroinfl or a hurdle model

Source: R/custom_tidiers.R
tidy_zeroinfl.Rd

A tidier for models generated with pscl::zeroinfl() or pscl::hurdle(). Term names will be updated to be consistent with generic models. The original term names are preserved in an "original_term" column.

Usage

tidy_zeroinfl(x, conf.int = TRUE, conf.level = 0.95, component = NULL, ...)

Arguments

x

(zeroinfl or hurdle)
A pscl::zeroinfl() or a pscl::hurdle() model.

conf.int

(logical)
Whether or not to include a confidence interval in the tidied output.

conf.level

(numeric)
The confidence level to use for the confidence interval (between 0 ans 1).

component

(string)
NULL or one of "all", "conditional", "zi", or "zero_inflated".

...

Additional parameters passed to parameters::model_parameters().
