mixnorm: The mixed normal distribution

Description

Density, distribution function, quantile function and random generation for the normal mixture distribution with means equal to 'mu' and standard deviations equal to 's'.

Usage

dmixnorm(x,p,mean,sd)
	pmixnorm(q,p,mean,sd)
	qmixnorm(prob,p,mean,sd)
	rmixnorm(n,p,mean,sd)

Arguments

x,q

vector of quantiles in dmixnorm and pmixnorm. In qmixnorm, 'x' is a vector of probabilities.

p

proportions of the mixture components.

prob

A vector of probabilities.

n

number of observations. If 'length(n) > 1', the length is taken to be the number required.

mean

vector of means

sd

vector of standard deviations
