Hi gretl prorammers,<br><br>despite the fact that I activated &quot;set warning off&quot;, I receive the message &quot;No observations would be left!&quot; after selecting an obviously non-existing panel data sample.<br>Actually I would expect no message at all in this case. Is this intended, or a &#39;bug&#39;? It is a bit annoying as it appears in the txt-output using the &#39;outfile&#39; command.<br>
<br>Best,<br>Artur<br>
