we derive the limit theory for this class of estimators. We find that subsampling is highly advantageous for estimators … subsampling is impotent, in the sense that subsampling has no effect on the asymptotic distribution. Perhaps surprisingly, for the … efficient smooth kernels, such as the Parzen kernel, we show that subsampling is harmful as it increases the asymptotic variance …
