One and two side generalisations of the log-Normal distribution by means of a new product definition

arXiv:0908.4334 · doi:10.1016/j.physa.2012.01.050

Abstract

In this manuscript we introduce a generalisation of the log-Normal distribution that is inspired by a modification of the Kaypten multiplicative process using the -product of Borges [Physica A \textbf{340}, 95 (2004)]. Depending on the value of q the distribution increases the tail for small (when ) or large (when ) values of the variable upon analysis. The usual log-Normal distribution is retrieved when . The main statistical features of this distribution are presented as well as a related random number generators and tables of quantiles of the Kolmogorov-Smirnov. Lastly, we illustrate the application of this distribution studying the adjustment of a set of variables of biological and financial origin.
