Other surrounding values are okay. The complemented version works for some reason. Here's some test code {{{ #include #include int main() { boost::math::skew_normal_distribution<> dist(2.0, 1.0, -2.5); std::vector qs = { 0.05, 0.075, 0.1 }; for(auto q : qs) { std::cout << ""q : "" << q << std::endl; std::cout << ""w/o complement: "" << quantile(dist, q) << std::endl; std::cout << ""w complement: "" << quantile(complement(dist, 1 - q)) << std::endl << std::endl; } } }}} Dunno how easy this is to fix. I can work around it where I'm using it, but it seems like something that could be fixed. Thanks!",Bugs,closed,To Be Determined,math,Boost 1.66.0,Problem,obsolete,,
