Abstract :
The Maxwell-Dagum distribution is a continuous statistical distribution
suitable for modeling data sets relating to various fields including finance, business,
medical sciences, survival analysis, and related areas. This article aimed to propose
some important properties of the Maxwell-Dagum distribution and obtained the parameters
of its estimates by using different methods of estimation including maximum
likelihood estimation, the maximum product of spacings, least squares estimation, and
weighted least squares estimation. The first and second derivatives of this distribution
are studied. We present two real data sets relating to the COVID-19 mortality rate
belonging to Canada and the waiting time of bank customers to assess the performance
of the proposed distribution. It is discovered that the Maxwell-Dagum distribution can
be chosen as the best distribution by having a minimum value of Akaike information
and Bayesian information criteria.
