percentage of range

capam — Tue, 30 Jan 2018 20:40:23 GMT

Hi,

In the code below min_stat, max_stat, and range are computed correctly, however, pc_stat doesn't work.

data have;
	do until (last.SO);
		set have;
		by unit SO;
		min_stat = min(min_stat, distance);
		max_stat = max(max_stat, distance);
	end;

	range = max_stat - min_stat;

	pc_stat = (distance-min_stat)/range;
	do until (last.SO);
		set have;
		by unit SO;
		output;
	end;
run;

The data below shows the input, incorrect pc_stat_get and the desired pc_stat_want. The typical excel equation is:J2 =(D2-F2)/H2 where distance = D2, min_stat = F2, range = H2, and pc_stat_want = J2. Thanks.

I think your formula is correct, not sure it's in the correct location. Try moving the RANGE to your DoW portion and the PC_STAT to after the second SET statement.

The RANGE calculation is fine.

The PC_STAT calculation should go just before the OUTPUT statement.

I'm not sure the WANT example is entirely correct for PC_STAT. Shouldn't each group have an observation where PC_STAT is 1?
