  • Laplace distribution;
  • parameter estimation;
  • probability density function;
  • random number;
  • variate


The Laplace distribution is often known as the double-exponential distribution. In modeling, the Laplace provides a heavier tailed alternative to the normal distribution. This chapter discusses probability density function and distribution function for the Laplace variate. It describes the variate relationships, parameter estimation and random number generation for the Laplace variate.
