gammainc(z,nu) = 1 - igamma(nu,z)/gamma(nu)represents the regularized lower incomplete gamma function in terms of the upper incomplete gamma function. igamma(nu,z) = gamma(nu)*(1 - gammainc(z,nu))represents the upper incomplete gamma function in terms of the regularized lower incomplet...
Some properties of the regularized lower incomplete gamma function are: limx→∞P(x,a)=1 for a≥0 limx,a→0P(x,a)=1 Tips When the regularized upper incomplete gamma function is close to 0, specifying the'upper'option to calculate the function is more accurate than subtracting the ...
The gamma cdf is p=F(x∣a,b)=1baΓ(a)x∫0ta−1e−tbdt. The result p is the probability that a single observation from a gamma distribution with parameters a and b falls in the interval [0,x]. The gamma cdf is related to the incomplete gamma function gammainc by f(x∣a,...
