A comparison of the multivariate classification using two methods. (a) The classification accuracy of the two methods with different variables selected; (b) The box plots of the classification accuracy. The 'Weight factor' in the plots refers to ${\alpha }_1$, in the range of [0.3, 0.6]; step length = 0.02. (a) CR by using SRVS method (b) CR by using Li et al.'s method
