Wild bootstrap in RCA(1) model. (English) Zbl 1248.62155

Summary: A heteroskedastic autoregressive process of first order is considered where the autoregressive parameter is random and errors are allowed to be non-identically distributed. A wild bootstrap procedure to approximate the distribution of the least-squares estimator of the mean of the random parameter is proposed as an alternative to the approximation based on asymptotic normality; and the consistency of this procedure is established.
