The method of orthogonal polynomial regression was used for regression modeling, and then the regression equations and regression coefficients were tested for significance.
采用正交多项式回归分析法建立回归模型，并对回归方程和回归系数进行显著性检验。

The coefficients are Fourier coefficients to the moment when the orthogonal functions are complex exponential functions.
若正交函数为复指数集，其系数正好是傅里叶系数。

In TISI, Long-Term Average Spectrum and Orthogonal Linear Prediction Coefficients are used as the feature parameters;
