Yegor Kozlov <[email protected]> changed: What |Removed |Added ---------------------------------------------------------------------------- Status|NEW |RESOLVED Resolution| |FIXED --- Comment #6 from Yegor Kozlov <[email protected]> 2010-07-26 08:24:56 EDT --- Thanks for the patch, applied in r979255 We had a debate whether to depend on commons-math or not and we think in the case of POISSON we can do without third party libraries, the implementation of Poisson distribution is really a few lines of code: private double probability(int k, double lambda) { return Math.pow(lambda, k) * Math.exp(-lambda) / factorial(k); } private double cumulativeProbability(int x, double lambda) { double result = 0; for(int k = 0; k <= x; k++){ result += probability(k, lambda); } return result; } Yegor -- Configure bugmail: https://issues.apache.org/bugzilla/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are the assignee for the bug. --------------------------------------------------------------------- To unsubscribe, e-mail: [email protected] For additional commands, e-mail: [email protected]
