Hi!
Need some help.
Have someone managed to create weighted percentile calculations in Visual Analytics ?
If so, could you please show some examples how to create them ?
We are working with Viya 3.5 and SAS VA 8.5.1.

I follow on that.
I think you can only achieve it if you duplicate the observations by their weight.
data public.weight(promote=yes);
input x wt;
datalines;
1 0.25
1.9 0.05
2.2 0.15
3.0 0.25
3.7 0.15
4.1 0.10
5 0.05
;
data public.weight1(promote=yes);
set public.weight;
decimals=input(scan(put(wt,best32.),2,'.'), best32.);
do i=1 to decimals;
output;
end;
drop i;
run;
I am not familiar with computing weighted percentiles in SAS VA, but I don't think Arne's proposal will give the correct estimates.
Thanks for your answers.
It seems to be difficult to create the weighted percentile calculations in Visual Analytics. We will try some more, otherwise we have to pre-aggregate the values before landing in VA.
