Additionally, respondents may be more prone to round off or up due to social desirability. By ignoring the heaping process a severe bias in terms of spikes and bumps is introduced when applying kernel density methods naively to the rounded data. A generalized Stochastic Expectation Maximization (SEM) approach accounting for heaping with potentially asymmetric rounding behaviour in univariate kernel density estimation is presented in this work. The introduced methods are applied to survey data of the German Socio-Economic Panel and exhibit very good performance simulations.","24 S.","https://refubium.fu-berlin.de/handle/fub188/19972||http://dx.doi.org/10.17169/refubium-23401","eng","urn:nbn:de:kobv:188-fudocsseries000000000319-4||urn:nbn:de:kobv:188-fudocsseries000000000006-7","http://www.fu-berlin.de/sites/refubium/rechtliches/Nutzungsbedingungen","Heaping||Survey Data||Measurement error||Self-reported data||Kernel density estimation||Rounded data","300 Sozialwissenschaften::330 Wirtschaft","Kernel Density Estimation for Heaped Data","Buch","open access","Wirtschaftswissenschaft","FUDOCS_derivate_000000005368","FUDOCS_document_000000023061","2015,27 : Economics","Diskussionsbeiträge des Fachbereichs Wirtschaftswissenschaft der Freien Universität Berlin"
