The night before one of my exams I needed to generate few numbers with Erlang probability distribution. When I googled for some kind of online generator I was quite taken aback by the fact that I couldn't find any (correct me if I'm wrong :-) ). So I decided to write my own generator and put it online and - here it is.
Currently, you can generate numbers from these probability distributions:
You can specify how many numbers do you want the generator to generate, formatting, the generator resolution, output type, the probability distribution itself and its parameters.
The generator can output the generated numbers to the page (for browsing/viewing) or generate a text file for you to download.
