Jean-Marc BARDET (Paris I) “”Non-Parametric Estimation of Time Varying AR(1)-Processes with Local Stationarity and Periodicity”.
Abstract: Extending the ideas of Dalhaus (2012), this paper aims at providing a kernel based
non-parametric estimation of a new class of time varying AR (1) processes (), with local
stationarity and periodic features (with a known period T), inducing the definition =
(/) −1 + for ∈ ℕ and with + ≡ . Central limit theorems are established
for kernel estimators ̂() reaching classical minimax rates and only requiring low order
moment conditions of the white noise() up to the second order.
