说明：  多元多项式回归，即一个程序，一个程序，对于给定的数据确定最小误差平方多项式。输出值也可能被转化运用Logit变换，从而使多元logistic回归。如何应用此程序的简要描述，可以发现在C源码包文件中的倒退/ EX / README。
(A program for multivariate polynomial regression, i.e., a program that determines a minimum squared error polynomial for given data. The output values may also be transformed with the logit transformation, thus enabling (multivariate) logistic regression. A brief description of how to apply this program can be found in the file regress/ex/readme in the C source package.)
