Statistical measurements of the performance of the multinomial models on a real dataset of newly sequenced genomes, Benin and Nigeria*

Locale Accuracy† Matthews correlation coefficient‡
Northern Ouémé 91.44% 0.608*
Southern Ouémé 91.73% 0.637*
Nigeria (Ogun State) 86.25% 0.371**

†Sum of the true positive and true negative divided by the total population.
‡Contingency matrix method of calculating the Pearson product–moment correlation coefficient (27). Its value ranges from −1 to +1 with +1 being a perfect positive prediction model, 0 no better than random prediction, and −1 being a model where predicted class is in total contradiction with observed class. Values indicated the strength of the relationship (*, strong positive relationship; **, moderate positive relationship).
