Debiased Estimators in High-Dimensional Regression: A Review and Replication of Javanmard and Montanari (2014)
高维回归中的去偏估计:Javanmard 与 Montanari (2014) 的综述与复制
High-dimensional statistical settings ($p \gg n$) pose fundamental challenges for classical inference, largely due to bias introduced by regularized estimators such as the LASSO. To address this, Javanmard and Montanari (2014) propose a debiased estimator that enables valid hypothesis testing and confidence interval construction. This report examines their debiased LASSO framework, which yields asymptotically normal estimators in high-dimensional settings. The key…
