I get a warning for rule #2, however, I cannot see why. Is there something in my underlying data set that could affect the script?</P><P><span class="lia-inline-image-display-wrapper lia-image-align-inline" image-alt="Sine_Topp_0-1576241054410.png" style="width: 400px;"><img src="https://community.jmp.com/t5/image/serverpage/image-id/20638i7840CF3EBDD6003C/image-size/medium?v=v2&amp;px=400" role="button" title="Sine_Topp_0-1576241054410.png" alt="Sine_Topp_0-1576241054410.png" /></span></P><P>&nbsp;</P> Fri, 13 Dec 2019 12:44:41 GMT https://community.jmp.com/t5/Discussions/Nelson-rules/m-p/238456#M47108 Sine_Topp 2019-12-13T12:44:41Z https://community.jmp.com/t5/Discussions/Nelson-rules/m-p/238477#M47115 <P>Is it possible you have points hidden but not excluded?</P> Fri, 13 Dec 2019 16:20:57 GMT https://community.jmp.com/t5/Discussions/Nelson-rules/m-p/238477#M47115 cwillden 2019-12-13T16:20:57Z https://community.jmp.com/t5/Discussions/Nelson-rules/m-p/239048#M47240 <P>No, I have some data point hidden AND excluded. When I remove them the Nelson warning disappears.
