Self-Weighted Estimation For Local Unit Root Regression With Applications, Zhishui Hu, Nan Liu, Peter C. B. Phillips, Qiying Wang Apr 2024

Self-Weighted Estimation For Local Unit Root Regression With Applications, Zhishui Hu, Nan Liu, Peter C. B. Phillips, Qiying Wang

Cowles Foundation Discussion Papers

A new self-weighted least squares (LS) estimation theory is developed for local unit root (LUR) autoregression with heteroskedasticity. The proposed estimator has a mixed Gaussian limit distribution and the corresponding studentized statistic converges to a standard normal distribution free of the unknown localizing coefficient which is not consistently estimable. The estimator is super consistent with a convergence rate slightly below the OP (n) rate of LS estimation. The asymptotic theory relies on a new framework of convergence to the local time of a Gaussian process, allowing for the sample moments generated from martingales and many other integrated dependent sequences. A …
