Compute the gamma function, given the value of the shape parameter z. The gamma function is a foundational element of many probability distributions, and hence plays a critical role in a wide variety of analytics calculations.
Compute the area under the gamma function from zero to the upper limit of integration x, given the upper limit of integration and the shape parameter s. The incomplete gamma function plays a critical role in computing many of the statistics that are commonly used in analytics studies.
Compute the regularized lower incomplete gamma function, given the upper limit of integration x and the value of the shape parameter s. The regularized incomplete gamma function plays a critical role in computing many of the statistics that are commonly used in analytics studies.
Compute the regularized upper incomplete gamma function, given the lower limit of integration x, and the value of the shape parameter s. The regularized incomplete gamma function plays a critical role in computing many of the statistics that are commonly used in analytics studies.
Compute the area under the gamma function from the lower limit of integration x to positive infinity, given the lower limit of integration and the shape parameter s. The incomplete gamma function plays a critical role in computing many of the statistics that are commonly used in analytics studies.
