ibeta error for fisher f distribution
Reported by: | nyberg72@… | Owned by: | johnmaddock |
---|---|---|---|
Milestone: | To Be Determined | Component: | math |
Version: | Boost 1.52.0 | Severity: | Problem |
Keywords: | beta function,, root finding, fisher f distributiond | Cc: |
Description
The following call sequence
#include <boost/math/distributions/fisher_f.hpp>
int main () {
double p = 3.0000000000000008e-068; Just an example, other very small values for p give the same error
boost::math::fisher_f_distribution<double> fd(2.0, 9.0);
double F = boost::math::quantile(boost::math::complement(fd, p));
return 0;
}
Will throw
Error: Error in function boost::math:ibeta<long double>(long double, long double, long double): Root finding evaluation exceeded 200 iterations, giving up now.

(In [83512]) Fix edge case in Halley iteration where the derivative is flatlining. Fix edge cases in poisson distribution quantile. Fixes #8314. Fixes #8308. Update and regenerate docs.
