Getting next non missing value for the same variable

Sas_R — Wed, 18 Sep 2013 21:56:51 GMT

Hello,

I have a question for getting the next non missing value for the same variable, in other words I'm trying to move up the non missing values so my missing value will be at the bottom of the variable. Below table is the example that I'm trying to create, how can I do that with SAS procedure ? Thank you.

X	Y	Y_New
1	5	5
2	.	7
3	7	6
4	6	.

Maybe your example is oversimplified... but this would do it :

data want;

set have(keep=x);

if not endy

then set have(keep=y where=(y is not missing)) end=endy;

else call missing(y);

run;

data y;
set in (keep=y where=(y^=.));
ord=_n_;

Hi..

Im not sure the result, in which scenario do you really want.. here is the simple code using many to many merge..

data have;

input x y ;

cards;

1 5

2 .

3 7

4 6

5 .

6 .

7 3

;

run;

proc print data = have;

run;

data want;

merge have(keep = x) have(keep = y where = (y is not missing));

run;

proc print;

run;

Thanks,

Yash
