DOI: 10.1080/01621459.2019.1611586

Abstract: Abstract Length-biased data are often encountered in cross-sectional surveys and prevalent-cohort studies on disease durations. Under length-biased sampling subjects with longer disease durations have greater chance to be observed. As a result, covariate values linked… read more here.

DOI: 10.1080/03610926.2016.1205621

Abstract: ABSTRACT In this article we prove a central limit theorem for the Lp distance where μ is a weight function and fn is the kernel density estimator proposed by Jones (1991) for length-biased data. The… read more here.

DOI: 10.1080/03610926.2018.1473613

Abstract: Abstract This paper considers non linear wavelet estimation on risk for the derivatives of regression function in Besov spaces based on biased data. It turns out that the convergence rate of non linear wavelet estimator… read more here.

DOI: 10.1080/10485252.2017.1339309

Abstract: ABSTRACT Length-biased data are a particular case of weighted data, which arise in many situations: biomedicine, quality control or epidemiology among others. In this paper we study the theoretical properties of kernel density estimation in… read more here.
