Journal ArticleDOI
Penalized Composite Quasi-Likelihood for Ultrahigh-Dimensional Variable Selection
TL;DR: A data‐driven weighted linear combination of convex loss functions, together with weighted L1‐penalty is proposed and established a strong oracle property of the method proposed that has both the model selection consistency and estimation efficiency for the true non‐zero coefficients.
Journal ArticleDOI
Regularization for Cox's proportional hazards model with NP-dimensionality
TL;DR: Strong oracle properties of non-concave penalized methods for non-polynomial (NP) dimensional data with censoring in the framework of Cox's proportional hazards model are established.
Journal ArticleDOI
Regularization for cox's proportional hazards model with np-dimensionality.
TL;DR: In this article, the authors established strong oracle properties of non-concave penalized methods for non-polynomial (NP) dimensional data with censoring in the framework of Cox's proportional hazards model.
Journal ArticleDOI
Linear Hypothesis Testing in Dense High-Dimensional Linear Models
Yinchu Zhu,Jelena Bradic +1 more
TL;DR: In this article, the authors propose a methodology for testing linear hypothesis in high-dimensional linear models, which does not impose any restriction on the size of the model, i.e. model sparsity or the loading vector representing the hypothesis.
Journal ArticleDOI
Cultivating Disaster Donors Using Data Analytics
TL;DR: There is evidence that mailed appeals are more effective when they emphasize disaster preparedness and training efforts over post-disaster cleanup, and a simple design strategy based on these insights has potential to improve success rates from 5.4% to 8.1%.
