where x is the random variable, μ is the location parameter, and b is the scale parameter.
The Laplace distribution is a probability distribution that is defined by two parameters: the location parameter (μ) and the scale parameter (b). The distribution is characterized by a "bump" at the center and two exponential tails. The probability density function (PDF) of the Laplace distribution is given by:
What is the difference between the Laplace and Gaussian distributions?

Common questions about the Laplace distribution
The Laplace distribution is particularly useful in scenarios where data follows a continuous distribution with a finite range. In the US, this is often seen in economic and financial modeling, where data may exhibit heavy tails and outliers. The Laplace distribution's ability to capture these characteristics makes it an attractive option for modeling financial returns, stock prices, and economic indicators. Furthermore, the Laplace distribution is also used in image and signal processing, where it helps in removing noise and enhancing image quality.

The Laplace distribution is similar to the Gaussian distribution in that both are continuous distributions. However, the Laplace distribution has a heavier tail than the Gaussian distribution, which makes it more suitable for modeling data with outliers.
In simpler terms, the Laplace distribution works by modeling the data as a mixture of two exponential distributions, one with a positive and one with a negative slope. This allows the distribution to capture the characteristics of both symmetric and asymmetric data.
