Diagnostics for Smoothing Splines
推导了适用于平滑样条的诊断度量，研究其性质，重点检测对拟合有显著影响的观测值，提供残差分析之外的额外信息，并用数值示例说明。
SUMMARY Diagnostic measures appropriate for use with smoothing splines are derived and their properties are investigated. The proposed measures focus on detection of observations which substantially influence the fit and provide additional information over that obtained from examination of residuals alone. A numerical example illustrates the technique.
