Get model parameters from zero-inflated and hurdle models
Source:R/get_parameters_zi.R
get_parameters.zeroinfl.Rd
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
data(mtcars)
m <- lm(mpg ~ wt + cyl + vs, data = mtcars)
