In MixtureFitting: Fitting of Univariate Mixture Distributions to Data using Various Approaches

Log-likelihood for Skew-Normal Mixture

Description

Calculates log-likelihood for a given data vector using a skew-normal mixture distribution.

Usage

    llsnmm( x, p )

Arguments

x

data vector

p

parameter vector of 4*n parameters, where n is number of mixture components. Structure of p vector is p = c( omega1, omega2, ..., omegan, dzeta1, dzeta2, ..., dzetan, sigma1, sigma2, ..., sigman, lambda1, lambda2, ..., lambdan ), where omegai is the proportion of i-th component, dzetai is the location of i-th component, sigmai is the scale of i-th component and lambdai is the shape of i-th component.

Value

log-likelihood
