Application of near infrared spectroscopy of feces to discriminate between adult male and female captive giant pandas (Ailuropoda melanoleuca) housed in US zoos.

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*Within a group, percentage of correct identifications differ from 50% (P**Within a group, percentage of correct identifications differ from 50% (P
