Our goal is to derive the distribution of $T$ based on an iid sample of $X_T$. Belomestny and Schoenmakers (2015) propose a solution based the Mellin transform in case where $X$ is a Brownian motion. Applying their technique we construct a non-parametric estimator for the density of $T$ for a self-similar one-dimensional process $X$. We calculate the minimax convergence rate of our estimator in some examples with a particular focus on Bessel processes where we also show asymptotic normality.", "revisions": [ { "version": "v1", "updated": "2019-05-24T11:53:21.000Z" } ], "analyses": { "subjects": [ "62G07", "62G20", "60G18", "60G40" ], "keywords": [ "stopped self-similar random processes", "stopping times", "estimation", "unknown random time independent", "self-similar one-dimensional process" ], "note": { "typesetting": "TeX", "pages": 0, "language": "en", "license": "arXiv", "status": "editable" } } }
