因为数据不是正台分布，我想用bootstrap做回归分析
stata默认的指令，bootstrap, reps(100) : reg Y X 是nonparametric （说明文件：This method is commonly referred to as thenonparametric bootstrap.）
我用help搜没找到关于parametric的指令，还请赐教，谢谢！

另外，nonparametric & parametric的区别是什么呢，我看paper: The advantage of the non-parametric modelslies in the control of outliers, but the disadvantage is that information isreduced during the process of ranking the continuous variables.
不是太理解，难道用nonparametric就不用控制异常值了吗？
