Hi everyone, I was comparing a colleague’s MATLAB code to my version (we are coding in parallel, and I am using Julia. I am also trying to convince him to move to Julia. Making progress… :slight_smile: ), and I noticed that the beta function returns something different for large x or y. Because of …

To build on other’s answers that express beta() as \Gamma(p)\Gamma(q)/\Gamma(p+q), it seems you can trivially reproduce Matlab’s behavior in Julia using loggamma() : julia> p = beta1 3.6e13 julia> q = 1/alpha1 + 1 2.7746751786287764 julia> exp(loggamma(p) + loggamma(q) - loggamma(p+q)) 4.473779306…
