GaussianDistributionMonoid

object GaussianDistributionMonoid extends Monoid[GaussianDistribution]

This monoid stems from the fact that if X and Y are independent random variables that are normally distributed, then their sum is also normally distributed, with its new mean equal to the sum of two means and variance equal to the sum of two variances. http://en.wikipedia.org/wiki/Sum_of_normally_distributed_random_variables

    Returns an instance of T calculated by summing all instances in iter in one pass. Returns None if iter is empty, else Some[ T].

    returns

    None if iter is empty, else an option value containing the summed T
