%description
The two-parameter Xgamma and Poisson Xgamma distributions are analyzed,
covering standard distribution and regression functions, maximum
likelihood estimation, quantile functions, probability density and mass
functions, cumulative distribution functions, and random number
generation. References include: "Sen, S., Chandra, N. and Maiti, S. S.

distribution. Journal of Statistical Theory and Applications, 17(4):
