Webparametric bootstrap is exactly the same as the simulation approach. In general, if there is a function t such that Varq(qb) = t(q); X1;:::;Xn are iid from Fq then Var bq (qb ) = t(qb); X 1;:::;X n are iid from F b Hence, the parametric bootstrap is simply the substitution approach. If bqis consistent and t is continuous, then Var qb (qb) is ...
