<p class="MsoNormal"><span style="font-size:11.0pt;font-family:"Calibri","sans-serif";color:#1F497D">Yes, one can calculate statistics such as the RMSE (and others) in GrADS. You can build expressions to calculate averages, sums of squares etc fairly easily,
e.g. using the “define” command.<o:p></o:p></span></p>

<p class="MsoNormal"><span style="font-size:11.0pt;font-family:"Calibri","sans-serif";color:#1F497D">But, depending on the nature of your data, I have to say that sometimes this kind of thing can become pretty hard work in GrADS and might better be done in
another package (or Python + GrADS via pygrads) that is better suited to number crunching. That’s my view anyway!<o:p></o:p></span></p>

<p class="MsoNormal"><span style="font-size:11.0pt;font-family:"Calibri","sans-serif";color:#1F497D">It depends on how complicated the statistical methods become – RMSE and the likes are potentially fine in GrADS, fitting complicated distributions is probably
better done elsewhere. <o:p></o:p></span></p>
