Find Beta distribution parameters with mode

Calculates the necessary parameters for the beta distribution to give the desired mode and certainty, k

find_beta_prior_mode(mode1, k)

Arguments

mode1	the desired mode
k	the desired certainty in the prior, must be at least 2. The higher this number, the "stronger" the prior

Value

a list with alpha and beta parameters for the Beta distribution
