make_noise: Draw random values from an assortment of distributions

In DataScienceForPublicPolicy/hypML: unitrootML - Machine Learning-Based Hypothesis Testing for Time Series

Description

Draw random values from an assortment of distributions

Usage

make_noise(
  n = 1,
  mu = 0,
  sd = 1,
  hi_lo = 1,
  error_type = "gaussian",
  symmetric = TRUE
)

Arguments

n	Number of observations Default = 1.
mu	Mean. Default = 0.
sd	Standard deviation. Default = 1.
hi_lo	A value to represent maximum value and minimum value for binomial distribution. or uniform distribution. A value of 2 will set a maximum of +2 and a minimum of -2. Default = 1.
error_type	Error distribution. Options include "gaussian", "binomial" and "uniform".
symmetric	Boolean indicating whether simulate symmetry. Default = TRUE. When FALSE, an absolute value is applied to the noise parameter to force assymmetry

Value

A numeric value or vector

Examples

#Draw 100 from a binomial distribution of -3 and 3
make_noise(n = 100, error_type = "binomial", hi_lo = 3)

#Draw 1 value from a Gaussian distribution N(2,10)
make_noise(n = 1, error_type = "gaussian", mu = 2, sd = 10)
