In this work we characterize two independent non-degenerate positive random variables X and Y to be gamma distributed with the same scale parameter by the assumptions ...
We define the incomplete gamma function ratio for positive N by \begin{align*}\tag{1}P(N, b, X) &= \int^X_0 t^{N-1}e^{-bt} dt/ \int^\infty_0 t^{N-1}e^{-bt} dt ...
