Abstract
Let the random variablesX1X2 X n be generated by the firstorder autoregressive modelX i =θX i−1 +e i wheree i i=1 2 n are iid random variables with mean zero variance σ2 and with unspecified density functiong· In the present paper we obtain a characterization of limiting distributions of nonparametric and parametric estimators of θ as well as a local asymptotic minimax bound of the risks of estimators
