Abstract: In this paper, we consider a stationary autoregressive AR(p) time series $$y_t=\phi _0+\phi _1y_{t-1}+\cdots +\phi _{p}y_{t-p}+u_t$$yt=ϕ0+ϕ1yt-1+⋯+ϕpyt-p+ut. A self-weighted M-estimator for the AR(p) model is proposed. The asymptotic normality of this estimator is established, which includes… read more here.

Abstract: The case-cohort study design is an effective way to reduce cost of assembling and measuring expensive covariates in large cohort studies. Recently, several weighted estimators were proposed for the case-cohort design when multiple diseases are… read more here.
