<p>Hi,</p>
<p>the CDF_2008 b-jet shapes analysis (unvalidated) requires some<br>
protection for YODA::Profile<b>Bin</b>1D.stdErr() because of this:</p>
<blockquote>
<p>terminate called after throwing an instance of
'YODA::LowStatsError'<br>
what(): Requested variance of a distribution with only one
effective entry<br>
</p>
</blockquote>
<p>I don't see a function that tells me the number of effective
entries for Profile<b>Bin</b>1D.<br>
<br>
Any thoughts on how to deal with that?</p>
<p>One would either need a protection on analysis level or change<br>
the behaviour of stdErr such that it doesn't throw an exception.</p>
