StatsGammaCDF

StatsGammaCDF (x, µ, σ, γ)

Returns the gamma cumulative distribution function (CDF) given by

$$\displaystyle F(x ; \mu, \sigma, \gamma)=\frac{\Gamma_{\text {inc }}\left(\gamma, \frac{x-\mu}{\sigma}\right)}{\Gamma(\gamma)} . \quad \begin{array}{c} x \geq \mu \\ \sigma,\gamma > 0 \end{array}$$

where Γ is the gamma function and Γ_inc is the incomplete gamma function gammaInc(γ,(x-µ)/σ, 0).
