In this work, we acquaint four parametric Topp-Leone Dagum distribution using the Topp-Leone-I (Type-I Topp-Leone) G class of distribution. We obtain some basic statistical properties, incomplete rth moments, mean deviation from mean, reliability and income inequality measures of the distribution, from graphical point of view we provide plots both its density and decreasing hazard function with assumed parametric values. We find Renyi and Tsallis entropies as well. We examine both parameter estimation methods, probability weighted moments and maximum likelihood. In the end we suggest four applications where this distribution is considered as best fitted model to the sub models of Dagum distribution and other related models in which Burr, Log-Dagum, generalized Dagum and Lomax distributions are include.
