摘要：In this article, we will use the quadratic rank transmutation map (QRTM) in order to generate a .exible family of probability distributions in which a three parameter Dagum distribution is embedded. Various structural properties of the new distribution including explicit expressions for the moments, random number generation and order statistics are derived. Estimation by maximum likelihood and inference for large samples are addressed. It will be shown that the analytical results are applicable to model the real world data.
