rmixlnorm: Generating Random Data From A Lognormal Mixture Model

In mixR: Finite Mixture Modeling for Raw and Binned Data

Description

The function rmixlnorm generates random data from a lognormal mixture model.

Usage

rmixlnorm(n, pi, mu, sd)

Arguments

n	a positive integer specifying the number of observations we want to generate from the mixture model
pi	a numeric vector for the proportion of each component
mu	a numeric vector for the mean of each component
sd	a numeric vector for the standard deviation of each component

Details

The number of random data from each component n_0 (a vector) is generated from a multinomial distribution Multinom(n, pi). Then the random data from each component is generated with the sample sized specified in n_0 and parameters of lognormal distributions specified in mu and sd.

Value

The function rmixlnorm returns a numeric vector of random data from the specified lognormal mixture model.
