Description

dzim is used to fit dynamic zero-inflated models.

Usage

dzim(
  formula,
  data,
  subset,
  na.action,
  weights = 1,
  offset = 0,
  control = dzim.control(...),
  ...
)

Arguments

formula	an objective of class "formula".
data	an optional dataframe, list or environment containing the variables in the model.
subset	an optional vector specifying a subset of observations to be used in the fitting process.
na.action	a function which indicates what should happen when the data contain NAs.
weights	an optional vector of 'prior weights' to be used in the fitting process.
offset	this can be used to specify a priori known component to be included in the linear predictor during fitting.
