  In this paper, we introduce and study the size-biased form of Kumaraswamy
distribution. The Kumaraswamy distribution which has drawn considerable
attention in hydrology and related areas was proposed by Kumarswamy. The new
distribution is derived under size-biased probability of sampling taking the
weights as the variate values. Various distributional and characterizing
properties of the model are studied. The methods of maximum likelihood and
matching quantiles estimation are employed to estimate the parameters of the
proposed model. Finally, we apply the proposed model to simulated and real data
sets.
