REIMS species classification accuracy for sex and maturity. REIMS spectra were acquired for faecal samples from sexually mature and immature mice of both sexes, and the entire data set was analysed in terms of the ability to discriminate sex or maturity. The distribution of the linear discriminant function for sex (a) and age (b) indicates the overlap between the categories, and the performance matrices (c, d) summarise the performance statistic using random forest classification. For the classification of age, the faecal samples were categorised in terms of the quality of the prediction, based on 10 random forest constructions (e)
