Algorithm discriminates with explicit confidence the alternative reproductive tactics (ARTs) in dimorphic mating systems with bimodal trait size distributions such as in the male horn polyphenisms in beetles. The bimodal distribution is parameterized by normal mixture distributions or facing gamma mixture distribution models. Likelihood of the alternative tactics for a given trait size is computed from the mixture models. Algorithm computes MLE of distribution parameters and the morph ratio.
Algorithm computes maximum likelihood estimates of the parameters of either the normal mixtuture distribution or the facing gamma distribution model for a dimorphic trait.
