Nonparametric density estimators based on nonstationary absolutely regular random sequences. (English) Zbl 0897.62036
Summary: The central limit theorems for the density estimator and for the integrated square error are proved for the case when the underlying sequence of random variables is nonstationary. Applications to Markov processes and ARMA processes are provided.
