@Reeza  It looks like the problem lies in the commented-out syntax. When I run it w/o specifying details about the x and y axis, I get this graph:   proc sgplot data=want_means; series x=timepoint y=promis_pain_intensity_Mean / lineattrs=(thickness=3px) markers markerattrs=(size=10pt); /* yaxis */ /* values=(3 to 15 by 1) label='PROMIS Pain Intensity Score (Mean)' */ /* labelattrs=(size=14pt weight=bold color=gray33) */ /* valueattrs=(size=14pt weight=bold color=gray33) */ /* offsetmin=0 offsetmax=0 grid minor minorcount=1; */ /* */ /* xaxis */ /* values=(0 to 2 by 1) label='Timepoint' */ /* labelattrs=(size=14pt weight=bold color=gray33) */ /* valueattrs=(size=14pt weight=bold color=gray33) */ /* offsetmin=0 offsetmax=0 grid minor minorcount=1; */ format Timepoint $timepoint_.; run; Maybe you could point me in the direction of some alternative syntax for customizing the axes?   Thanks!   ...

Does the log help explain why the means aren't showing up on the graph? ... View more

Also, how would I incorporate a group variable in the proc means that would also be output to the new dataset? For example, if I wanted to plot the change in means of males and females? ... View more

This is great. Thank you! A few other questions. The syntax below seems to work, but I can't seem to figure out the proc sgplot syntax.   Proc means data=kb.data_01 maxdec=1; var age promis_pain_intensity promis_pain_interference ; class timepoint; title "Descriptive Statistics for Continuous Measures"; ods output summary = want_means; run; proc print data=want_means; var promis_pain_interference_Mean promis_pain_intensity_Mean; by timepoint; run;                       I've done my best to adapt the code from the desired robslink.com page, but the means aren't plotted on the graph (see below). ods graphics / attrpriority=none; proc sgplot data=want_means aspect=1 noautolegend; styleattrs datasymbols=(diamondfilled squarefilled) datacontrastcolors=(navy magenta) datalinepatterns=(solid); series x=timepoint y=promis_pain_interference_Mean / lineattrs=(thickness=3px) markers markerattrs=(size=12pt); yaxis values=(4 to 20 by 1) label='PROMIS Pain Interference Score (Mean)' labelattrs=(size=16pt weight=bold color=gray33) valueattrs=(size=16pt weight=bold color=gray33) offsetmin=0 offsetmax=0 grid minor minorcount=3; xaxis values=(0 to 2 by 1) label='Timepoint' labelattrs=(size=16pt weight=bold color=gray33) valueattrs=(size=16pt weight=bold color=gray33) offsetmin=0 offsetmax=0 grid minor minorcount=3; run; quit; ODS HTML CLOSE; ODS LISTING; Any clues in my syntax?

Yes, there are formats, but I still can't figure it out.

@jiltao What I don't understand is why you would need to input a difference in the means or input the mean values themselves (w/ no difference between them?) if you are testing for no difference?   The difference in the means is 0 when testing for null difference, correct? The group means could be any value, as long as they were the same value, correct? Examples: group 1: 10, group 2: 10 group 1: 100, group 2: 100   proc power uses the mean difference in the calculation, either as a result of the user inputting a mean difference or by subtracting one inputted mean from the other. It makes sense to me that these values would be required if I was testing for a mean difference other than zero (i.e., null difference), but not if I was testing for no difference.    What am I missing here?   Should I input the same values I would input if I was selecting "Difference between means" or "Group means", instead of selecting "Difference between means, null difference" or "Group means, null difference"   Thanks for your help here! ...

Thanks for your response. It won't run without a value in that field...And, the sample size changes when you input different mean difference values. ... View more

<The mean difference refers to the two conjectured / sample group means. > But why would I input a mean difference when I am testing for no difference? In other words, if the null difference is zero, why is it asking for a difference other than zero? ... View more
