Title: | Relative density estimation and local bandwidth selection for censored data | Authors: | Cao, Ricardo JANSSEN, Paul VERAVERBEKE, Noel |
Issue Date: | 2001 | Publisher: | ELSEVIER SCIENCE BV | Source: | COMPUTATIONAL STATISTICS & DATA ANALYSIS, 36. p. 497-510 | Abstract: | This paper is concerned with local bandwidth selection for a kernel-type estimator of the relative density (or grade density) when the samples come from two populations under a right random censorship mechanism. A two-stage smoothed plug-in local bandwidth selector with a beta reference is proposed. This estimation procedure is used to analyze the lifetime density in a two-sample problem related to breast cancer. A simulation study is carried out to examine the practical performance of the bandwidth selector. | Document URI: | http://hdl.handle.net/1942/200 | ISSN: | 0167-9473 | e-ISSN: | 1872-7352 | DOI: | 10.1016/S0167-9473(00)00055-4 | ISI #: | 000169264700005 | Category: | A1 | Type: | Journal Contribution | Validations: | ecoom 2002 |
