Simulate random error

Description

Simulate random error

Usage

baSimuError(
  n,
  error.type = c("normal", "skewed"),
  sig = 1,
  mu = 0,
  skew.mu = NULL,
  skew.phi = NULL,
  skew.noise = 0.001
)

Arguments

`n`	sample size
`error.type`	normal or skewed
`sig`	standard deviation
`mu`	mean
`skew.mu`	if skewed, by how much
`skew.phi`	if skewed, by how much
`skew.noise`	if skewed, contains how much noise

Details

Skewed distribution: Prameterization: mu, phi; RNBINOM uses (n,p) with: phi = n, mu = n(1-p)/p; Mean: mu = n(1-p)/p #; Variances: mu(1+mu/phi) = n (1-p)/p^2
