A Note on the Generalised Cross-Validation Criterion in Linear Model Selection
从坐标无关的角度推导出一个新的广义交叉验证准则，它包含了普通交叉验证和现有广义交叉验证准则作为特例。
Cross-validation criteria in linear model selection are approached from a coordinate free point of view. A new generalised cross-validation criterion is derived and shown to contain the ordinary and the existing generalised cross-validation criteria as special cases.
