中文摘要：

在两个潜变量的偏最小二乘法（PLS）基础上，研究了如何将PLS算法从两个潜变量扩展到多个潜变量的一套完整方法（包括具体的形式规范和迭代步骤）；以及在多个潜变量PLS算法上的符号检验．并在MATLAB上实现了完整的多个潜变量PLS算法，验证了该迭代方法的有效性．

英文摘要：

This paper presents a method, which extends PLS（partial least square） algorithm from two-LV （latent variable） to multi-LV based on two-LV PLS algorithm, including detailed formal specification and iterative procedure. This paper also discusses the sign test of muhi-LV PLS algorithm. The author designed a program for multi-LV PLS algorithm using the iterative procedure based on MATLAB software. As a result, it demonstrates the validity of the iterative procedure.
