In probability theory and statistics, the xgamma distribution is a continuous probability distribution having one unknown parameter. It is introduced and studied by Subhradev Sen et al. on 2016. The xgamma distribution is a special finite mixture of one parameter exponential distribution and gamma distribution with shape parameter 3 and a general scale parameter. The distribution is useful in modeling time-to-event data sets coming from Reliability and Survival Analysis.
