Published in 2017 at "Metrika"

DOI: 10.1007/s00184-016-0592-x

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.

Published in 2018 at "Environmental Research"

DOI: 10.1016/j.envres.2018.02.020

Abstract: &NA; Temperature‐mortality relationships are nonlinear, time‐lagged, and can vary depending on the time of year and geographic location, all of which limits the applicability of simple regression models in describing these associations. This research demonstrates… read more here.

Published in 2019 at "Regional Science and Urban Economics"

DOI: 10.1016/j.regsciurbeco.2019.01.002

Abstract: The interaction matrix, or spatial weight matrix, is the fundamental tool to model cross-sectional interdependence between observations in spatial autoregressive models. However, it is most of the time not derived from theory, as it should… read more here.

Published in 2019 at "Communications in Statistics - Theory and Methods"

DOI: 10.1080/03610926.2019.1649428

Abstract: Abstract This paper considers variable selection for spatial autoregressive models based on the minimum prediction error criterion. Firstly, based on an initial consistent estimator, a new loss function is constructed from the perspective of prediction,… read more here.

Published in 2020 at "Econometric Reviews"

DOI: 10.1080/07474938.2021.1899504

Abstract: Abstract Models characterized by autoregressive structure and random coefficients are powerful tools for the analysis of high-frequency, high-dimensional and volatile time series. The available literature on such models is broad, but also sector-specific, overlapping, and… read more here.
