We derive asymptotic expressions for the bias and the variance of the estimator and show that the squared bias term dominates the variance term. This coincides with results that are available for non-contaminated observations. We then discuss the selection of the bandwidth parameter when estimating integrated squared density derivatives based on contaminated data. We propose a data-driven bandwidth selection procedure of the plug-in type and investigate its finite sample performance via a simulation study.<\/jats:p>","DOI":"10.1111\/1467-9868.00366","type":"journal-article","created":{"date-parts":[[2003,3,12]],"date-time":"2003-03-12T19:37:40Z","timestamp":1047497860000},"page":"869-886","source":"Crossref","is-referenced-by-count":51,"title":["Estimation of Integrated Squared Density Derivatives from a Contaminated Sample"],"prefix":"10.1093","volume":"64","author":[{"given":"A.","family":"Delaigle","sequence":"first","affiliation":[{"name":"Universit\u00e9 catholique de Louvain , Louvain-la-Neuve , Belgium"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"I.","family":"Gijbels","sequence":"additional","affiliation":[{"name":"Universit\u00e9 catholique de Louvain , Louvain-la-Neuve , Belgium"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"286","published-online":{"date-parts":[[2002,10,23]]},"reference":[{"key":"2023040109514585500_","volume-title":"Estimation of integrated squared density derivatives","author":"Aldershof","year":"1991"},{"key":"2023040109514585500_","doi-asserted-by":"crossref","first-page":"1184","DOI":"10.1080\/01621459.1988.10478718","article-title":"Optimal rates of convergence for deconvolving a density","volume":"83","author":"Carroll","year":"1988","journal-title":"J.
