摘要 用非参数估计方法,在一元函数的核密度估计的基础上,给出了二元函数的核密度估计形式,并通过计算估计量的MISE的最小值得出最优窗宽. The form of the kernel density estimation of two-dimensional function based on the kernel density estimation of function is given by using nonparametric estimation, and the best bandwidth is discussed through minimizing the mean of the integrated squared error(MISE).
