[提问]如何进行稳健性检验

用bootstrap方法再做一次，看看变化如何

恩 谈的有些道理，但是不是很全面很系统。

学习了，很重要

mark一下，蛮有用的

推荐module to perform robustness check of alternative specifications
即"CHECKROB"

感觉还不错用。
作者说明如下：
checkrob estimates a set of regressions where the dependent
      variable is regressed  (with whatever method is specified in
      estimation command) on core variables - which are  included in
      all regressions - and all possible combinations of other
      (non-core) variables.  For each regression the coefficients,
      their standard errors and optional estimation return variables
      (ereturn list) are recorded in a comma separated format which can
      be accessed  after the execution of checkrob. It is a useful tool
      if you want to check the robustness of  including/excluding one
      or more controls in your preferred specification. The command is
      similar (though simpler) to the command rcheck by Kenneth L.
      Simons but can handle some  multiple equation estimation commands
      (i.e. heckman). checkrob was used to produce the  robustness
      results in Barslund et al. (2007).
