Create a hurdle Poisson specification

Usage

hurdle_poisson(formula = NULL)

Arguments

formula

Optional formula for the hurdle probability (P(Y > 0)). If NULL, uses intercept-only model.

Value

A ratiod_zi object

Examples

# Intercept-only hurdle
hurdle_poisson()
#> tulpaRatio Zero-Inflation Specification
#> ==================================
#> Type: Hurdle Poisson 
#> Formula: ~ 1 (intercept only)

# Hurdle probability depends on effort
hurdle_poisson(~ effort)
#> tulpaRatio Zero-Inflation Specification
