A generalization of hypergeometric and gamma functions

Al-saqabi et al. [4] defined a gamma-type function and its probability density function involving a confluent hypergeometirc function φ1 of two variables [7],where and discussed some of its statistical functions. we propose extension of φ1 by introducing more parameters in following form: we then define gamma-type function involving newly defined hypergeometric function of two variables and discuss its probability density function along with some of its associated statistical functions. we use inverse mellon transform technique to derive closed form of gamma-type function and moment generating function. © 2013 pakistan journal of statistics.
