Do you know for roughly what range of n the binomial_distribution provided
becomes very slow? It would be useful to know whether computing for, say, n
approx. 10 or 100 would be efficient.
I need to generate from a multinomial for a stochastic simulation. n is
unlikely to be very large, however this generation (as well as some based on
the gamma distribution) will need to be done at every time step and
thousands of simulations would need to be executed. For this reason I would
like to make this generation step as efficient as possible.
Will it be a while before version 1.47 is released?
