Density function of a mixture of Gaussian univariate distributions

Description

This function computes the density function of a mixture of Gaussian univariate distributions

Usage

GaussianMixturePdf(x, mu, sigma, w)

Arguments

x	Points at which the density is comptuted (n x 1);
mu	vector of means for each regime (r x 1);
sigma	vector of standard deviations for each regime (r x 1);
w	vector of the probability of each regime (r x 1).

Value

f	Values of the distribution function
