  This article presents a bootstrap approximation to the Lp_statistics of
kernel density estimator in length-biased model. Length-biased data arise in
many situations, such as survival analysis, renewal processes and physics. The
article establishes a bootstrap central limit theorem for the corresponding
bootstrap version of this Lp_statistic. The bootstrap is a widely used tool in
statistics and, therefore, the properties of this bootstrap approximation are
of great interest in applied as well as in theoretical statistics.
