rcn {npsm}

random contaminated normal deviates

Description

Generate a random sample from a contaminated normal distribution.

Usage

rcn(n, eps, sigmac)
rcn_5_5(n)

Arguments

n

sample size

eps

proportion of proportion of contamination

sigmac

standard devation of contaiminated component

Details

With probability (1-eps) a deviates are drawn from a standard normal distribution. With probability eps deviates are drawn from a normal distribution with mean 0 and standard devation sigmac rcn_5_5 is a special case where eps=0.05 and sigma=5.

Value

n x 1 numeric vector containing the random deviates.
