Abstract
This paper is devoted to the Restimation problem for the parameter of a stationary ARMA model. The asymptotic uniform linearity of a suitable vector of rank statistics leads to the asymptotic normality of √nconsistent Restimates resulting from the minimization of the norm of this vector. By using a discretized √nconsistent preliminary estimate, we construct a new class of onestep Restimators. We compute the asymptotic relative efficiency of the proposed estimators with respect to the LS estimator. Efficiency properties are investigated via a MonteCarlo study in the particular case of an AR(1) model.
