Hi,   my data is something like   country       1990       1991        1992       1993    Burundi        3.01         .                .            0.66    Canada          .           0.12            .            2.11     and now I want to replace the missing value by the follow non-missing value.   my code is data replace1; set co2_emission_id; array [*] '1990'n-'2014'n; do i=1990 to dim(''n); if ''n{i}=. then ''n{i}= ''n{i+1}; end; run;   I think there is a name needed between array and [*] so I can modify the do loop.  But my data variable names are numbers so I don't know what I should put there.   May I have a suggestion for that? Thank you ... View more

Hi, I have upload my question. And I know how to sketch the normal distribution but just have no idea how to color the confident interval. My code is   data Q4; do mean=0; do x=-5 to 5 by .01; y=pdf('normal',x,mean,1); output; end; end; run; proc sgplot data=Q4; band x=x lower=0 upper=y / group=mean transparency=.5; series x=x y=y / group=mean; run;   I think I need to modify the "band" there but don't know how. Anyone could help me with that??   Thank you! ... View more
