get_parameters.zeroinfl: Get model parameters from zero-inflated and hurdle models

Description

Returns the coefficients from a model.

Usage

# S3 method for zeroinfl
get_parameters(
  x,
  component = c("all", "conditional", "zi", "zero_inflated"),
  ...
)
# S3 method for zcpglm
get_parameters(
  x,
  component = c("all", "conditional", "zi", "zero_inflated"),
  ...
)
# S3 method for mhurdle
get_parameters(
  x,
  component = c("all", "conditional", "zi", "zero_inflated", "infrequent_purchase",
    "ip", "auxiliary"),
  ...
)

Arguments

x

A fitted model.

component

Should all predictor variables, predictor variables for the conditional model, the zero-inflated part of the model, the dispersion term or the instrumental variables be returned? Applies to models with zero-inflated and/or dispersion formula, or to models with instrumental variable (so called fixed-effects regressions). May be abbreviated. Note that the conditional component is also called count or mean component, depending on the model.

...

Currently not used.

Value

For models with smooth terms or zero-inflation component, a data frame with three columns: the parameter names, the related point estimates and the component.

Examples

# NOT RUN {
data(mtcars)
m <- lm(mpg ~ wt + cyl + vs, data = mtcars)
get_parameters(m)
# }
