Problem with DistNormalInv

Reported by: Christian Paz Owned by: Víctor de Buen Remiro
Priority: normal Milestone:
Component: Math Version: head
Severity: critical Keywords:

Description

The function DistNormalInv is giving unexpected results.

Real b=DistNormalInv(0.77, 0.5, 0.1);

returns -1.#INF while in previous versions it returned 0.5738846849 which is
logical.

Thanks
Christian

Resolution: → fixed
Status: new → closed

Bug has been fixed.
Gaussian distribution is now using gsl_cdf_ugaussian... functions.
But I don´t now the reason it was using very old cdf* functions in a wrong way.
