Hello!

I ran into maybe a bug, I am starting out with the example for MultinomialDistribution.

But when i call Generate on it, it throws an argument exception with Argument cannot be negative. Parameter name: n.

But N is 5 in the example.

Is this a bug or am i doing something wrong?


			int numberOfTrials = 5;
			double[] probabilities = { 0.25, 0.75 };
			
			// Create a new Multinomial distribution with 5 trials for 2 symbols
			var dist = new MultinomialDistribution (numberOfTrials, probabilities);			try
			{
				var test = dist.Generate();
			} catch(ArgumentException es)
			{

				//HERE We have an Argument cannot be negative. Parameter name: n
			}
