翻译后摘要:可变跨度散点图平滑的基础上局部线性拟合。局部交叉验证用于估计作为横坐标值的函数的最佳跨度。一个拒绝规则建议,使平滑抵抗离群值。计算效率的算法,利用更新公式和相应的FORTRAN子程序。
Abstract : A variable span scatterplot smoother based on local linear fits is described. Local cross-validation is used to estimate the optimal span as a function of abscissa value. A rejection rule is suggested to make the smoother resistant against outliers. Computationally efficient algorithms making use of updating formulas and corresponding FORTRAN subroutines are presented.
