提出了基于小波核函数的偏最小二乘方法对混沌信号进行了有效拟合，得到了很好的效果。-Based on wavelet kernel function of the partial least squares method of fitting the effective chaotic signal obtained very good results.

后向偏最小二乘方法matlab的实现，完全是自己参照公式编的哦-After the partial least squares method matlab realize, is entirely their own formulas reference to the Oh

可以对光谱数据进行预处理，除了偏最小二乘法之外，也有一些其他方法(Besides the partial least square method, there are also some other methods)
