Comparison of identification accuracies of PC-LDA models including seven or five age classes based on either all male, all female or mixed sample sets. A variety of PC-LDA models were built in OMB based on sample sets differing in specimen sex and number of age classes. Number of samples in each age category specified for all three models. Females only: 1 day (n = 148), 3 day (n = 148), 5 day (n = 151), 9 day (n = 149), 13 day (n = 151), 15 day (n = 150), 20 day (n = 31). Males only: 1 day (n = 60), 3 day (n = 60), 5 day (n = 60), 9 day (n = 59), 13 day (n = 60), 15 day (n = 59) or 20 day (n = 25). Females and Males mixed: 1 day (n = 208), 3 day (n = 208), 5 day (n = 211), 9 day (n = 208), 13 day (n = 211), 15 day (n = 209) or 20 day (n = 56).
