Abstract The confluent hypergeometric function kind 1 random variable has the probability density function proportional to x v−1 1 F 1(α;β;−x). In this article, we study several properties of this distribution. We also derive density functions of X 1 / X 2, X 1 / (X 1 + X 2) and X 1 + X 2 where X 1 and X 2 are independent confluent hypergeometric function kind 1 and gamma variables, respectively.
