Table 3 Comparative success of four different statistical models aiming to predict male An. gambiae age group as a function of their reproductive morphology (Table 2). Overall success indicates the percent of a given data set (original or blind trial) whose age-grade was correctly predicted by the model; with age-specific success indicating the proportion of 'young' and 'old' males correctly classified within these groups.
