Notes: The overall maximum convergence ratio of the model is below 0.25 in all years, indicating a satisfactory convergence of the algorithm. In addition, the goodness of fit is above 0.05 in all years, indicating that the average values are close to the values observed in the data (Ripley et al. 2015).
