Abstract: | We prove a functional central limit theorem for the empirical process of a stationary process Xt=Yt+Vt, where Yt is a long memory moving average in i.i.d. r.v.s s, s t, and Vt=V (t, t-1,...) is a weakly dependent nonlinear Bernoulli shift. Conditions of weak dependence of Vt are written in terms of L2-norms of shift-cut differences V (t, t-n, 0,...,) – V(t,...,t-n+1, 0,...). Examples of Bernoulli shifts are discussed. The limit empirical process is a degenerated process of the form f(x)Z, where f is the marginal p.d.f. of X0 and Z is a standard normal r.v. The proof is based on a uniform reduction principle for the empirical process. |
