Linear discriminant analysis (LDA) applied to mosquito species of the subgenera Anopheles, Nyssorhynchus, Anopheles (Kertezia) neivai and Chagasia bathana. a Plot of the training set for all species projected over the first three components of the LDA. b Plot of the test set for all species projected over the first three components of the LDA. c Plot of the test set in the Nyssorynchus subgenera compared to the Anopheles (Kertezia) neivai and Chagasia bathana species, projected over the first three components of the LDA. d Plot of the test set in the Anopheles subgenera compared to the Anopheles (Kertezia) neivai and Chagasia bathana species projected over the first three components of the LDA. These 3D plots represent only one of the 500 Monte Carlo iterations performed with the algorithm. The algorithm had a 93.33% global positive identification rate
