WebbThe asymmetric Laplace distribution, including the special case of =, is an example of a geometric stable distribution. It represents the limiting distribution for a sum of independent, identically distributed random variables with finite variance and covariance where the number of elements to be summed is itself an independent random variable distributed … Webb4 nov. 2024 · A symmetric Laplace distribution has already been extended to the multivariate case: McGraw and Wagner ( 1968) listed a bivariate Laplace distribution as a special case of elliptically contoured law, while Johnson and Kotz (1970) provided its density function. The same distribution appeared in Anderson ( 1992) as a special case … Webb4 nov. 2013 · Abstract: A mixture of shifted asymmetric Laplace distributions is introduced and used for clustering and classification.

Since the distribution has finite moments of all orders, explicit formulas for density and distribution functions, the asymmetric Laplace …

WebbIt has been argued that the Laplace distribution fits most things in nature better than the normal distribution. There are many extensions to the Laplace distribution, such as the asymmetric Laplace, asymmetric log-Laplace, Laplace (re-parameterized for precision), log-Laplace, multivariate Laplace, and skew-Laplace, among many more.
