p_value.zcpglm: p-values for Models with Zero-Inflation

Description

This function attempts to return, or compute, p-values of hurdle and zero-inflated models.

Usage

# S3 method for zcpglm
p_value(model, component = c("all", "conditional", "zi", "zero_inflated"), ...)
# S3 method for zeroinfl
p_value(
  model,
  component = c("all", "conditional", "zi", "zero_inflated"),
  method = NULL,
  verbose = TRUE,
  ...
)

Arguments

model

A statistical model.

component

Model component for which parameters should be shown. See the documentation for your object's class in model_parameters() for further details.

method

For linear mixed models, method can be "kenward" or "satterthwaite".

Toggle warnings and messages.

Value

A data frame with at least two columns: the parameter names and the p-values. Depending on the model, may also include columns for model components etc.

Examples

# NOT RUN {
if (require("pscl", quietly = TRUE)) {
  data("bioChemists")
  model <- zeroinfl(art ~ fem + mar + kid5 | kid5 + phd, data = bioChemists)
  p_value(model)
  p_value(model, component = "zi")
}
# }
