Our results are established assuming a weakly dependent Bernoulli shift structure for the underlying observations, which contains most stationary functional time series models, under mild conditions. As a corollary, we obtain joint asymptotics for functional principal components computed from empirical long run covariance operators, showing that they have the favorable property of being asymptotically independent.", "revisions": [ { "version": "v1", "updated": "2015-03-02T21:05:19.000Z" } ], "analyses": { "keywords": [ "asymptotic normality", "kernel estimators", "functional time series models", "stationary functional time series", "dependent bernoulli shift structure" ], "note": { "typesetting": "TeX", "pages": 0, "language": "en", "license": "arXiv", "status": "editable" } } }
