Selective Inference for Group-Sparse Linear Models

Fan Yang, Rina Foygel Barber, Prateek Jain, John Lafferty

摘要:

我们开发的工具,选择性推理组稀疏的设置,包括建设的置信区间和p值测试选定的变量组。我们的主要技术结果给出了精确的分布的数据到一个给定的子空间的投影的幅度,并使我们能够开发推理程序的广泛的一类组稀疏的选择方法,包括组套索,迭代硬阈值,向前逐步回归。我们给出数值结果来说明这些工具的模拟数据和健康记录数据。

英文摘要:

We develop tools for selective inference in the setting of group sparsity, including the construction of confidence intervals and p-values for testing selected groups of variables. Our main technical result gives the precise distribution of the magnitude of the projection of the data onto a given subspace, and enables us to develop inference procedures for a broad class of group-sparse selection methods, including the group lasso, iterative hard thresholding, and forward stepwise regression. We give numerical results to illustrate these tools on simulated data and on health record data.
