Comment: Hierarchical Statistical Modeling for Paleoclimate Reconstruction
评论:古气候重建的层级统计建模
The article by Bo Li, Douglas W. Nychka, and Caspar M. Ammann (hereafter, LNA) has several goals. It considers the important problem of reconstruction of past (over a period of more than 1000 Years Before Present) climate from multiproxy data, and it directly recognizes the various uncertainties in this undertaking.
