標題: | Choice of the bandwidth ratio in Rice's boundary modification | 作者: | Cheng, Ming-Yen | 關鍵字: | boundary effect;boundary kernel;exact mean squared error;kernel smoothing;local linear smoothing | 公開日期: | 2006 | 起(迄)頁: | 235-251 | 來源出版物: | 中國統計學報,44 | 摘要: | Rice (1984) proposed a boundary modified kernel regression method which linearly combines two kernel regression estimators based on different bandwidths. In the context of density estimation, advantages of this method over two other popular approaches, local linear fitting & the boundary kernels of M¨uller (1991), are discussed. Selection of the ratio of the two bandwidths is studied. Asymptotic & exact mean squared errors are provided as tools to analyze the problem. In the case of Normal kernels, keeping the bandwidth ratio fixed, for ease & speed of implementation, & a specific bandwidth ratio are suggested. |
