gammaDistributionCompl

The Γ distribution and its complement

The Γ distribution is defined as the integral from 0 to x of the gamma probability density function. The complementary function returns the integral from x to ∞

gammaDistribution = ($(INTEGRATE 0, x) tb-1e-at dt) ab/Γ(b)

x must be greater than 0.
