模型选择是统计学的热点研究问题。近年来随着数据维数越来越高,传统模型选择方法的应用受到了很多制约。本文着重介绍高维模型选择的新方法,并讨论实现模型选择过程的一个重要环节,即调整参数的选取。最后文章总结归纳了未来可能的研究方向。
Model selection is an important issue in Statistics. Traditional model-selection methods, however, meet difficulties with the increasing of data dimension. This paper is devoted to the survey of the model selection methods for high-dimensional data. The choice of tuning parameters is also discussed. Some future research directions are provided.
