WebFeb 13, 2024 · I have an algorithm which needs to calculate the difference of two Gamma distributions evaluated at some large values. I cannot do this over CDFs because they give $1$ if a large value is evaluated. Then the difference of the CDFs is always $0$.Getting a difference of zero is breaking down my code at the optimzation stage. WebJul 28, 2005 · A difference in means is simple to understand, and is unambiguously defined at least if the distributions have means, even for real-life long-tailed distributions. Inference from the t-test is quite accurate even a long way from normality and from equality of the shapes of the two distributions, except in very small sample sizes.
