In addition, the lowest values in MSE, AIC and BIC goodness of fit criteria, were obtained from the Janoschek function, followed by the Morgan Mercer Flodin function as the second best fit model in terms of MSE, AIC and BIC values (27.82, 41.08, 42.67, respectively) and the Logistic function as the third one (34.64, 45.09, 46.54, respectively).
