At the same time, nonparametric methods is certainly flexible in reducing modeling biases so that they become the most important methods of studying nonparametric model.
与之对应的非参数估计方法因其在减少建模偏差方面的灵活性而成为研究非参数模型的重要方法。

They emphasize for finding ’self-consistent’ smooth nonparametric curves that pass through the middle of a multidimensional data set, and we can get the frameworkof the data set.
主曲线是第一主成分的非线性推广，强调寻找通过数据分布的“中间”，并满足自相合的无参数光滑曲线，这些曲线给出了数据的概貌。
