Figure 3 in The maximum likelihood identification method applied to insect morphometric data

Figure 3. Classification based on harmonics. Values in percent are the proportions of correct assignments averaged over the complete set of data, mixing the various species, but restricted to the outline-based method. Each value is shown with an error bar which is its standard deviation. The left part shows the results from the maximum likelihood method applied to the perimeter of the contour and to the shape variables. The right part shows the average scores obtained with the Mahalanobis classification. Abbreviation: first PC— the shape variables used were the few first PC of shape variables that the MLi classification selected as the most discriminant set of PC; all PC—the maximum number of PC that could be used by the Mahalanobis classification.
