Hi,
Is there a was to compute an average under a certain condition?
For example say I have a modified version of sashelp.class with an additional record where individual has a weight of zero. I want to count this individual into his category, but exclude him from the calculated mean. Here is example code:
proc format;
value myfmt
low-99.999 = 'Light'
100-high = 'Heavy';
quit;
data class;
input (name sex) ($) age height weight;
output;
do until(done);
set sashelp.class end=done;
output;
end;
cards;
FriedEgg M 99 100 0
;
run;
proc report data=class;
column sex weight=status (Sum Mean),weight;
define sex / group;
define status / across format=myfmt. preloadfmt;
define weight / format=comma8.2;
compute after;
line ' ';
line 'Total Class Weight: ' weight.sum comma8.2;
endcomp;
run;
weight Sum Mean
sex Heavy Light weight weight
F 3 6 811.00 90.11
M 6 5 1,089.50 99.05
Total Class Weight: 1,900.50
Desired Output:
S
e Weight Sum Mean
x Heavy Light Weight Weight
F 3 6 811.00 90.11
M 6 5 1,089.50 108.95
Total Class Weight: 1,900.50
Sure. Of course.
You need to make a weight variable to exclude this obs.
proc format; value myfmt low-99.999 = 'Light' 100-high = 'Heavy'; quit; data class; input (name sex) ($) age height weight; flag=0; output; do until(done); set sashelp.class end=done; flag=1; output; end; cards; FriedEgg M 99 100 0 ; run; proc report data=class nowd; column sex weight=status (Sum Mean),weight; weight flag; define sex / group; define status / across format=myfmt. preloadfmt; define weight / format=comma8.2; compute after; line ' '; line 'Total Class Weight: ' weight.sum comma8.2; endcomp; run;

Thanks Ksharp,
Reporting procedures are my bane.
En. Yes. There is lots of thing you need to learn in proc report.
Actually I also spend lots of time to learn this proc which is more complicated than I imaged.
But Here. I will Thank Arthur.Carpenter who wrote a book about it which makes me to learn easily.
It is long time not seeing him here.
