Follow-up Comment #5, bug #47646 (project gsl): [From Yu] Patrick, I was thinking if it's worthwhile to allow the use of close-form cdf for some functions. Currently, the test routine calculates the expected probability in each bin using numerical integration of pdf. In this particular case,

Patrick, I was thinking if it's worthwhile to allow the use of close-form cdf for some functions. Currently, the test routine calculates the expected probability in each bin using numerical integration of pdf. In this particular case, it blows up. Using cdf in stead of integration can avoid the

Follow-up Comment #4, bug #47646 (project gsl): I'm also not sure how to properly test for this case, as the PDF integration test fails for these small arguments. ___ Reply to this item at:
