summary.tsizip: Summarizing a iZIP INGARCH Model Fit

In thomas-fung/izipr: Interpretable Zero-Inflated Poisson Models in R

Description

summary method for class tsizip.

Usage

## S3 method for class 'tsizip'
summary(object, ...)

## S3 method for class 'summary.tsizip'
print(
  x,
  digits = max(3, getOption("digits") - 3),
  signif.stars = getOption("show.signif.stars"),
  ...
)

Arguments

object	an object class 'tsizip', obtained from a call to tsglm.izip.
...	other arguments passed to or from other methods (currently unused).
x	a result of the default method of summary().
digits	numeric; minimum number of significant digits to be used for most numbers.
signif.stars	logical. If TRUE, ‘significance stars’ are printed for each coefficient.

Details

print.summary.tsizip tries to be smart about formatting the coefficients, standard errors and gives 'significance stars'. The coefficients component of the result gives the estimated coefficients and their estimated standard errors, together with their ratio. This third column is labelled as Z value as the dispersion is fixed for this family. A forth column gives the two-tailed p-value corresponding to Z value based on the asymptotic Normal reference distribution.

Value

summary.tsizip returns an object of class "summary.tsizip", a list containing at least the following components:

call	the component from object.
family	the component from object.
coefficients	the matrix of coefficients, standard errors, z-values and p-values.
df	a 3-vector of the rank of the model and the number of residual degrees of freedom, plus number of coefficients.
