Summary
LetXt, ...,Xn be random variables forming a realization from a linear process\(X_t = \sum\limits_{r = 0}^\infty {g_r Z_{t - r} } \) where {Zt} is a sequence of independent and identically distributed random variables with E|Zt|<∞ for some ε>0, andgr→0 asr→∞ at some specified rate. LetX1 have a probability density functionf. It is then established that for every realx, the standard kernel type estimator\(\hat f_n (x)\) based onXt (1≦t≦n) is, under some general regularity conditions, asymptotically normal and converges a.s. tof(x) asn→∞.
