Then we consider the problem of selecting the one from the ordinary sample quantile and the symmetric sample quantile. We propose the bootstrapping technique selecting the one with smaller estimator of asymptotic variance. We also compare the result through this technique with the theoretic correct one. This shows that bootstrapping technique is applicable. URI: http://140.113.39.130/cdrfb3/record/nctu/#NT860338015http://hdl.handle.net/11536/62710 Appears in Collections: Thesis
