Find beta parameters with maximum variance

Given a desired annual mean attack rate and the number of epochs to consider per year, gives the alpha and beta parameters with the desired mean but maximum variance

find_beta_prior_with_mean(desired_annual_mean, buckets)

Arguments

desired_annual_mean	the desired ANNUAL mean attack rate
the	number of buckets to split each year into

Value

a list with alpha and beta
