In this paper, we extend a class of semiparametric density estimators to time series context. The asymptotic theory and
simulation study are discussed. Theoretical results and numerical
comparison show that, in the time series case, the estimators in
this class are better than, or at least competitive with, the
traditional kernel density estimator in a broad class of densities. |
