title: Remove an entity in recursive regressions with a for loop
body: <p>I am running a panel data regression. I want to run a for loop to obtain regression results where every time one of the entities has been dropped, so that I can see, by comparing the different coefficients, whether my results are driven by a particular entity or they are consistent across the sample. I am currently using this for loop</p>
  <pre><code>forvalues i = 1/19{
  use &quot;sample_seven.dta&quot;, clear
  drop if countryid == i
  xtscc ln_gdp tech population inflation tradebalance i.year, fe}
  </code></pre>
  <p>However, when I run the above code what I get is 19 regressions where only two observations have been dropped in each of them.</p>
