Abstract: | Summary In recent years, the bootstrap method has been extended to time series analysis where the observations are serially correlated.
Contributions have focused on the autoregressive model producing alternative resampling procedures. In contrast, apart from
some empirical applications, very little attention has been paid to the possibility of extending the use of the bootstrap
method to pure moving average (MA) or mixed ARMA models. In this paper, we present a new bootstrap procedure which can be
applied to assess the distributional properties of the moving average parameters estimates obtained by a least square approach.
We discuss the methodology and the limits of its usage. Finally, the performance of the bootstrap approach is compared with
that of the competing alternative given by the Monte Carlo simulation.
