About procedures of classification:
All the procedures are explained in Pardo-Seco et al (2019). Please, contact A. Salas () for questions, comments, etc.
The database used for classification was taken from Purps et al. (2014). Note that this dataset was modified as detailed in Pardo-Seco et al. (2019).
The PCA-QDA classification procedure was reported by Egeland et al. (2004).
