Description

Generate a random sample from a mixture of normals.

Usage

rmix.norm(n, alpha, mu, sigma = rep(1,length(alpha)))

Arguments

n

sample size.

alpha

vector of mixture proportions of length m, the order of the mixture.

mu

vector of means of component distributions.

sigma

vector of standard deviations of component distributions, default value: sigma = rep(1,length(alpha)).

Value

Return a samples of size n from an m-component normal mixture.
