Hello all,<br><br>I am curious, what mean is obtained from this code snippet?<br><br>    boost::accumulators::accumulator_set&lt;int, boost::accumulators::features&lt;boost::accumulators::tag::mean&gt; &gt; Accumulator;<br>
    int Mean = boost::accumulators::mean(Accumulator);<br><br>It appears to be non-zero when I test it. Is there some way I can tell that the average was taken for an empty data set?<br><br>I was looking around in the documentation for the accumulator library, but was unable to find an answer to this question.<br>
<br>Thanks in advance!<br><br>-- Dylan<br>
