标题： Using statistical smoothing to date medieval manuscripts

摘要： 我们讨论使用多元核平滑方法来确定11世纪到15世纪期间英格兰埃塞克斯郡手稿的日期。 数据集包括大约3300份有日期的手稿和5000份无日期的手稿，前者被用作训练样本，以推断后者的日期。 假设在某种意义上，通过文档距离度量向量定义的“接近”手稿，将具有接近的日期。 使用这种方法，通过在距离度量之间进行平滑处理，运用统计学思想来评估“相似性”，从而根据有日期的手稿估计5000份无日期手稿的日期。 显示英文摘要

摘要： We discuss the use of multivariate kernel smoothing methods to date manuscripts dating from the 11th to the 15th centuries, in the English county of Essex. The dataset consists of some 3300 dated and 5000 undated manuscripts, and the former are used as a training sample for imputing dates for the latter. It is assumed that two manuscripts that are ``close'', in a sense that may be defined by a vector of measures of distance for documents, will have close dates. Using this approach, statistical ideas are used to assess ``similarity'', by smoothing among distance measures, and thus to estimate dates for the 5000 undated manuscripts by reference to the dated ones.
