Auxiliary for Controlling ZIM Fitting

Description

Auxiliary function for zim fitting. Typically only used internally by zim.fit, but may be used to construct a control argument for either function.

Usage

zim.control(
  dist = c("zip", "zinb"),
  method = c("EM-NR", "EM-FS"),
  type = c("solve", "ginv"),
  robust = FALSE,
  trace = FALSE,
  start = NULL,
  minit = 10,
  maxit = 10000,
  epsilon = 1e-08
)

Arguments

dist	count model family.
method	algorithm for parameter estimation.
type	type of matrix inverse.
robust	logical; if TRUE, robust standard errors will be calculated.
trace	logical; if TRUE, display iteration history.
start	initial parameter values.
minit	minimum number of iterations.
maxit	maximum number of iterations.
epsilon	positive convergence tolerance.
