【摘要】 密度核估计的局部窗宽选择法中,光滑Bootstrap法只有在目标函数具有较高阶的连续导数时,窗宽h才能获得理想的取值。为此,减弱条件提出了新的计算方法,经过证明分析该方法是较切合实际的。更多还原

【Abstract】 During the process of using partial window bandwidth selection for kernel density estimation,the window bandwidth h would achieve the ideal value only when the target density has the comparatively higher continuous derivative with smooth bootstrap.Therefore,a new way of calculation was put forward based on the reduction condition,and the selection was proved practical based on the analysis.更多还原
