PLS-DA法是将定量偏最小二乘法用于判别分析的一种策略，其基本思想是将已知类别样本的浓度阵分别设为0、1（对两类用PLS1方法而言），或-1、0、1（对三类用PLS1方法而言），或01、10（对两类用PLS2方法而言），或001、010、100（对三类用PLS2方法而言），多类问题依次类推，再通过定量PLS方法建立模型。(PLS- DA method is to use quantitative partial least squares discriminant analysis of a kind of strategy, the basic idea is to known categories the concentration of the sample matrix is set to 0, 1 (for two types of PLS1 method), or 1, 0, 1 (for three types of PLS1 method), or 01, 10 (for two types of PLS2 method), or 001, 010, 100 (for three PLS2 method), many questions so on, through quantitative PLS method to establish model.)
