zim.control

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.
