Abstract
In this paper empirical likelihood (EL)-based inference for a semiparametric varying-coefficient spatial autoregressive model is investigated. The maximum EL estimators for the parametric component and the nonparametric component are established. Furthermore, asymptotic properties of the proposed estimators and EL ratios are derived, and the corresponding confidence regions/bands are constructed. Their finite sample performances are studied via simulation and an example.
