Parzen窗函数法(方窗，正态窗，指数窗)进行数据估计。源码中包含对一维和二维数据的估计程序，同时还将iris、Yeast、abalone数据集绛为一维进行数据估计。-Parzen window functions is used to estimate the datasets(contains the one-dimensional datasets and the two-dimensional datasets). Besides, there are programs that change the datasets of iris、Yeast、 abalone dataset to the one-dimensional datasets and estimate the psf of them.
