Engineering applications, the interpolation and regression (curve fitting) function expression usually are used to describe data to solve the problem.
工程应用中通常用插值和回归(曲线拟合)解决函数表达式描述数据的问题。

The upper and lower envelopes are constructed by using LSSVM regression instead of spline interpolation in EMD.
同时以LSSVM回归方式形成包络线，以取代传统EMD中的三次样条插值；

Kriging interpolation maps for residuals were drawn. The residuals of classic regression and spatial regression had high consistency, and the distributions were in line with the soil nutrients.
