Annotatsiya

Bootstrap for nonlinear statistics like U -statistics of dependent data has been studied by several authors. This is typically done by producing a bootstrap version of the sample and plugging it into the statistic. We suggest an alternative approach of getting a bootstrap version of U -statistics. We will show the consistency of the new method and compare its finite sample properties in a simulation study and by applying both methods to financial data.
