I have been using the rannor function as:   eps1=rannor(1)*sqrt(feps1); eps2=rannor(2)*sqrt(feps2);     I have looked at examples (e.g., Rand (Normal)),  but it is not clear to me how to code my function. My question is how to properly code my sqrt(feps1) with the rand function for a normal distribution?   ... View more

I have the  following code which works well for a needle plot to which I added a Loess to connect certain points.  The Loess worked for 4 of the variables but I get an error message stating, " ERROR: No LOESS fit produced for group 'PAUC03L' because all computed smoothing criterion values are invalid. ERROR: No LOESS fit produced for group 'PAUC37L' because all computed smoothing criterion values are invalid."   The data is below and I have looked at it and can't figure out why SAS has an issue with the PAUC03L and PAUC37L data. They both decrease as they should.  title 'Confidence Interval Range Kfast'; proc sgplot data=boot2 ; /*highlow x=ratio low=low high=high / type=line;*/ loess x=ratio y=LOWER_ci/interpolation=cubic group=block; highlow x=ratio low=lower_ci high=upper_ci / type=bar group=block lineattrs=(color=black) name='a' attrid=Mono; yaxis label='CI range' grid; xaxis label='Ratio KaT/KaR' grid values =(0.5 to 2.1 by 0.1); keylegend 'a' / location=inside position=TOP; run; Can some one tell me what is wrong with the boot2 data for PAUC03L and PAUC37L for the Lower_CI?   Group Block Upper_CI Lower_CI Ratio 1 PAUC03L 84 80 0.62 1 PAUC03L 85 81 0.63 1 PAUC03L 88 85 0.7 1 PAUC03L 100 99 0.8 1 PAUC03U 108 106 1.25 1 PAUC03U 109 106 1.3 1 PAUC03U 113 109 1.5 1 PAUC03U 122 115 2 1 PAUC03U 125 116 2.1 1 PAUC37L 104 102 0.62 1 PAUC37L 104 101 0.63 1 PAUC37L 104 100 0.7 1 PAUC37L 90 88 0.8 1 PAUC37U 98 96 1.25 1 PAUC37U 96 95 1.3 1 PAUC37U 96 93 1.5 1 PAUC37U 94 89 2 1 PAUC37U 94 89 2.1 ...
