Add negative binomial distribution #60

Closed jmh530 closed 2 years ago

jmh530 commented 2 years ago

negativeBinomialInvCDF is a little time-consuming for extreme values in a naive implementation, even with a good guess. I took some inspiration from R's version of it to get it working in a more efficient manner for some extreme values, but it's not exactly the same. A simple copy of R's version also wouldn't pass the unittests, I think, even if I wanted it to. Some adjustments versus R's version enable it to pass UTs here.
