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"),
  ...
)

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.

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.
