Title: A THREE-PARAMETER POWER WEIGHTED SUJATHA DISTRIBUTION WITH PROPERTIES AND APPLICATIONS
Abstract: 
In the present paper a three parameter power weighted Sujatha distribution (PWSD), which includes weighted Sujatha distribution (WSD), power Sujatha distribution (PSD) and Sujatha distribution as particular cases, has been proposed and investigated. Its raw moments and central moments and moments based measures including coefficient of variation, skewness, kurtosis and index of dispersion have been obtained and discussed. Its reliability measures including hazard rate function and mean residual life function have been discussed. The estimation of parameters of the proposed distribution has been discussed using the method of maximum likelihood. Applications of the proposed distribution to some real lifetime datasets have been discussed. The goodness of fit of the proposed distribution shows quite satisfactory fit over other lifetime distributions.
