The effect of using fecal samples derived from “leaf only” bamboo diets on the ability of near infrared spectroscopy to discriminate between adult male and female captive giant pandas (Ailuropoda melanoleuca).

aResults are reported as: % correct identifications (number correct/group total). Within each discriminant model group, calibrations were developed using either the entire calibration set (100%), or with a reduced set (75%) after removing a randomly selected 25% of samples to be used as a validation set. A, B=random group.bRefers to the prediction of group membership for each sample in the calibration set itself.cRefers to the prediction of group membership for each sample in the validation set. NA=not applicable, i.e. there were no validation samples removed from the 100% calibration.**Within a group, percentage of correct identifications differ from 50% (P
