IREX VI: mixed-effects longitudinal models for iris ageing: response to Bowyer and Ortiz

Bowyer and Ortiz, in their study ‘A Critical Examination of the IREX VI Results’, make seven criticisms of the authors application of linear mixed-effects models to longitudinally collected iris recognition Hamming distances. We reject these as either irrelevant, misinterpretations, or qualitatively correct, but quantitatively irrelevant.
