问题 I have a problem where I want to generate a set of random integer values between 1 and 5 inclusive using a probability distribution. Poisson and Inverse Gamma are two distributions that show the characteristics I am after (majority at mean, less higher numbers) that I have found. I am looking at using Apache Commons Math but I wasn't sure how to generate the numbers I wanted using the distributions available. 回答1: From your problem description, it sounds like you actually want a sample

I'm trying to use the apache commons math library version 3.5+ to solve an optimization problem. Basically, I'm trying to fit a (gamma) distribution to some data points. I can't seem to find any simple examples of how to use the new (version 3.5) optimization tools, such as SimplexSolver, SimplexOptimizer, or OptimizationData, to solve a trivial optimization problem. Similar questions have been asked here before, but all the answers seem to be for older version of apache math - in 3.5 things were restructured and none of the example code I could find works. Does anyone have a working example
