Apache Commons RNG v1.0 is released

Hello. The Apache Commons Team is pleased to announce the availability of the first official release of "Apache Commons RNG". Apache Commons RNG provides Java implementations of pseudo-random numbers generators. The release notes can be reviewed at

Re: [math] Pearson Correaltion NaNs

Hello. I am having difficulties using the Pearson Correlation because it seems that it does not work if some cell is NaN. Is that intended? Very likely. [When NaN appears in a computation, it propagates and the result is NaN.] Here is some code: public static void main(String[] args) {

Hi. If you are using the function a * Math.pow(t, b) * Math.exp(-c * t) the gradient is: { Math.pow(t, b) * Math.exp(-c * t), a * Math.log(t) * Math.pow(t, b) * Math.exp(-c * t), -a * t Math.pow(t, b) * Math.exp(-c * t) } // No idea what goes here. Nothing seems to work. Well,
