These distributions provide data-modeling tools alternative to the use of the Laplace distribution, but they also have applications wherever absolute values of normal random variables appear, for example in relation to the absolute error of estimators and predictors, but also in Brownian motion theory. We provide Monte Carlo evidence related to the performance of maximum likelihood estimation of the distribution.54p.CC BY: Attribution alone 4.0https://creativecommons.org/licenses/by/4.0/Double half-normal distributionSkew normal distributionLaplace distributionDouble exponential distributionMaximum likelihoodText
