# S4 method for class 'zeroinfl'
extract(
  model,

  include.count = TRUE,
  include.zero = TRUE,
  include.aic = TRUE,
  include.loglik = TRUE,
  include.nobs = TRUE,
  ...
)

Arguments

model

A statistical model object.

beside

Arrange the model terms below each other or beside each other? The binary model parameters and the count parameters can be displayed in two separate columns of the table.

include.count

Report the count parameters in the coefficients block (before the binary part for the zeros)?

include.zero

Should the binary part of the model be included in the coefficients block (after the count parameters)?

include.aic

Report Akaike's Information Criterion (AIC) in the GOF block?

include.loglik

Report the log likelihood in the GOF block?

include.nobs

Report the number of observations in the GOF block?

...

Custom parameters, which are handed over to subroutines, in this case to the summary method for the object.
