Function Behavior notes
Logic for model analysisCollection of different models, each with a suite of associated methods. Current models are:
Methods
ChallengesTrouble getting convergence for maximum likelihood fits to simulation results. By throwing inf log likelihood with outofbounds parameters (should really set a limit epsilon rather than zero on alpha/sigma values using "LBFGSB" method) can avoid hard errors in optim, but mle throws hard errors and optim complains about convergence: "ERROR: ABNORMAL_TERMINATION_IN_LNSRCH", a convergence error of 52 in "LBFGSB" method.
