regmixPhiInit: regmixPhiInit

In hkasahar/normalregMix: normalregMix: An R Package for Normal Mixture Regression Models

Description

Generates lists of parameters for initial candidates used by the modified EM test for mixture of normals.

Usage

regmixPhiInit(y, x, z = NULL, parlist, h, tau, ninits = 1)

Arguments

y	n by 1 vector of data for y
x	n by q matrix of data for x
z	n by p matrix of regressor associated with gam
parlist	The parameter estimates as a list containing alpha, mu, sigma, and gam in the form of (alpha = (alpha_1, ..., alpha_m), mu = (mu_1, ..., mu_m), sigma = (sigma_1, ..., sigma_m), gam = (gam_1, ..., gam_m))
h	h used as index for pivoting
tau	Tau used to split the h-th component
ninits	number of initial values to be generated

Value

A list with the following items:

alpha	m+1 by ninits matrix for alpha
mubeta	q+1 by m+1 by ninits array for mu and beta
sigma	m+1 by ninits matrix for sigma
gam	m+1 by ninits matrix for gam
