<div>Dear NCL forum:</div>
<div> </div>
<div>I am trying to use <font style="background-color:rgb(255,255,0)" color="#000000"><strong>stat_dispersion</strong></font> function to compute 99th
percentile of data. At first, I tried the example 1 on the introduction page.
However, as you can see in the following, the outputs 22 to 26 are missing
values rather that the values shown on the web. My NCL is version 6.3.0. Is it
due to my installation issue or anyone can compute the 99th percentile without
problems?</div>
<div> </div>
<div>thanks for answering my question!</div>
