Hi, </div>
</div>
</div>
<div><font color="#0f61c8"><br>
</font>I just stumbled upon the following inconsistency. In the description of function stddev it is written that (<a href="http://www.ncl.ucar.edu/Document/Functions/Built-in/stddev.shtml">http://www.ncl.ucar.edu/Document/Functions/Built-in/stddev.shtml</a>)<br>
<font color="#0f61c8"><br>
</font><i> (…) this function calculates the population standard deviation.</i><br>
<font color="#0f61c8"><br>
</font>However, I’m afraid it does not compute the <b>population</b> std but rather the
<b>sample</b> std. Example program attached.<br>
<font color="#0f61c8"><br>
</font>I see two solutions: <br>
(1) either change the documentation, such that is states specifically this function computes the sample standard deviation (perhaps also add an explanation why this is better).<br>
(2) change the code . This will create a backward incompatibility and many user scripts may yield different results. </div>
<div><br>
</div>
<div>As a side note, function stdMonTLL also computes the sample std, second example program attached. <font color="#0f61c8"><br>
<br>
</font>Kind regards,<br>
Leo<br>
