calculates the Maximum Entropy (Harte (2011))
discrete probability distribution of a number of ordered
states (e.g., faces of a 6-sided die) given the mean of
many rolls. Here, this is merely used so that a single
parameter can control the probability distribution of
small versus large descendant areas during cladogenesis.
Value of the state (e.g., which of a number of faces on a die, or number of different size classes of geographic range)
Lambda parameter (Harte2011).
