Abstract

This work introduces a new proposed model, the exponentiated Rayleigh-Rayleigh distribution
created by Rayleigh-Rayleigh and exponentiated distributions. It better fits the data sets, whereas
other distributions could not be implemented. The peak over threshold method is considered for model fitting in the tailed distribution. The parameters estimation is the maximum likelihood estimate and measurements of model fitting are the Kolmogorov-Smirnov test, Anderson-Darling test, Akaike Information Criterion and Bayesian information criterion. The exponentiated Rayleigh-Rayleigh distribution is compared to the current distributions, which are lognormal, gamma, Weibull and generalized Pareto, exponential, exponential-exponential, gamma-exponential and Rayleigh-Rayleigh. The data are considered based on simulation and Danish Fire data. We have found that the Exponentiated Rayleigh-Rayleigh distribution is the better fit for the small size of the data.
