How to get the variable list in the descending order of their mean values？

TomiKong — Thu, 10 May 2012 16:03:21 GMT

For example, I have one dataset:mydata. How to get the variable list in which var1-var4 are sorted by the descending order of their mean values?

Thanks!!

data mydata;

input var1 var2 var3 var4;

datalines;

1 2 3 4

1 3 1 6

4 5 8 9

2 8 2 2

;

run;

Depend upon what you actually want. E.g., it might require something like the following if you actually want the dataset variables to be reordered:

data mydata;

input var1 var2 var3 var4;

datalines;

1 2 3 4

1 3 1 6

4 5 8 9

2 8 2 2

;

proc means data=mydata noprint;

output out=var_means(drop=_FREQ_ _TYPE_);

run;

proc transpose data=var_means out=trans_mean(rename=(_NAME_=NAME));

id _STAT_;

run;

proc sql noprint;

select name into :names

separated by " "

from trans_mean

order by mean desc

;

quit;

data want;

retain &names.;

set mydata;

run;
