sample regression function

基本解释

Regression software programs graph the sample points and give the (cost-function) formula of the straight line that best fits the points.
回归软件程序将样本点用图表示，并且给出最拟合样本点的直线的价值函数公式。
Instead of judgement which based on curve trend, we can get better estimate result by use the regression function in that small sample field.
再次，在时序数据预测时，结合模式匹配，得出小样本空间，以基于小样本的回归预测方法代替数据曲线趋势判断方法，以期得到更佳的预测结果。
The meaning of symbolic regression is that we are searching for a function that closely matches an unknown expression based on a finite set of sample data, in order to analyze and forecast data.
符号回归的含义是找出一个符号形式的数学公式，以指定的精度拟合相关变量的有限样本，以便于分析和预测。
