Title: Asymptotics of Distribution Estimation In Linear Autoregressive Models
Abstract: 
For the linear autoregressive stationary time series model, I consider estimation of the error distribution, including error variance, density and cumulative distribution functions. The asymptotic distribution of the error variance estimator is shown to be normal. And we also obtain the strong consistency of the proposed error variance estimator For the distribution of the error density estimator, at a fixed point, is shown to be normal. Globally, the asymptotic distribution of the maximum of a suitably normalized deviation of the density estimator from the expectation of the kernel error density (based on the true error) is the same as in the case of the one sample set up, which is given in Bickel and Rosenblatt (1973).
