WebThe gamma function, denoted by \Gamma (s) Γ(s), is deﬁned by the formula \Gamma (s)=\int_0^ {\infty} t^ {s-1} e^ {-t}\, dt, Γ(s) = ∫ 0∞ ts−1e−tdt, which is defined for all … WebWe consider specifically the density function f(x; a, v, p) = I I x-'- exp {--(x/a)'}/aPFr(v) (1) in which x is not negative and p is not zero. The other parameters are positive, and the symbol r(v) indicates the conventional Gamma function. This family of distributions differs from that of [8] in that it allows negative values for the parameter p.
