start_1: Starting values for (ZI)Poisson and (ZI)NegativeBinomial

In majuvi/llperm: LikeLihood based Permutation of Regression Residuals (PRR) test

Starting values for (ZI)Poisson and (ZI)NegativeBinomial

Description

This is part of the new implementation.

Usage

start_1(
  X,
  Y,
  Z = NULL,
  offsetx = 0,
  offsetz = 0,
  weights = 1,
  zero.inflated = FALSE,
  over.dispersed = FALSE
)

Arguments

X	model matrix for the count component
Y	response vector
Z	model matrix for the zero component
offsetx	offset for the count component
offsetz	offset for the zero component
weights	weights for each observation
zero.inflated	calculate starting values for the zero component?
over.dispersed	calculate starting values for the dispersion parameter?

Value

list of starting values for each component, and possible over-dispersion
