Computation :: Probability

combination(set,subset): Returns the number of unique subsets created from all combinations of a number of elements, or (-1) on error.

erf(x): Returns the value of erf(x), the "error function" or cumulative distribution function, which computes the probability that a Gaussian random number falls within a given range.

exp_dist(mean): Returns a random number with exponential distribution.

factorial(number): Returns the factorial of a given number.

gauss(mean,deviation): Returns a pseudo-random number with an exact Gaussian distribution.

permutation(set,subset): Returns the number of unique subsets created from all permutations of a number of elements in which the order of the chosen elements is significant, or (-1) on error.

random_weighted(p0 [, p1, ..., pN]): Returns a randomly selected index based on their given relative probabilities.

roll_dice(num,sides): Returns the sum of a number of die rolls using dice with a given number of sides.
