title: Stata: use of cluster or svy with standardized coefficients
body: <p>I got the recommendation to standardize my regression coefficients.
  I have never done it before, but I have seen it in papers, it seems quite common.
  At first sight it appeared quite simple, just adding the <code>beta</code> option to the <code>regress</code> command in Stata.</p>
  
  <p>However, since I have individuals in groups, I need to use the cluster <code>option</code> as well.
  Now Stata tells me that using both options together is not possible:
  <code>beta may not be specified with vce(cluster clustvar) or the svy prefix</code>.
  The manual does not say why. </p>
  
  <p>Using the user written command <code>listcoef</code> I can get the betas for my regression.
  The question now is, is this a computational problem Stata has and I can safely use the <code>listcoef</code> results or is this a statistical problem and I cannot use them or only under certain conditions.</p>
  
  <p>I cannot see a statistical reason why Stata should not be able to do this.
  My Google searches came up with other people having the same question, but no explanation of whether this is a statistical or computational problem.</p>
  
  <p>I am happy for any feedback. Potentially I used the wrong search terms?
  I cannot believe I am the first to wonder about this.</p>
