Hello!

I'd like to fill out a data set by 'a group'. The rule is, that if a column has a value within a group, its value should be filled in - forward AND backward.

The start data is:

Data Have;

Input N $ X1-X4;

Datalines;

A 1 . . .

A 1 . . .

A 1 . . .

A . 2 . .

A . 2 . .

B 1 . . .

B 1 . . .

B . . 3 .

B . . . 4

B . . . 4

C . 2 . .

C . 2 . .

C . . 3 .

;

Run;

The end data should be:

A 1 2 . .

A 1 2 . .

A 1 2 . .

A 1 2 . .

A 1 2 . .

B 1 . 3 4

B 1 . 3 4

B 1 . 3 4

B 1 . 3 4

B 1 . 3 4

C . 2 3 .

C . 2 3 .

C . 2 3 .

Thanks&kind regards

Is it at all possible that for any group any of the Xi could have 2 or more non-missing values? If so, what would the rule be?

Sorry ballardw, I didn't answer your question. You're right, there are at least 2 non-missing values. I need this a an intermediate result for a 'look-up' table (and hope I will finally get to my desired result).

Do you know how to get rid of those warnings? Update can in this case produce the same result without being warned unnecessary.

do _n_ =

update have(obs=

by n;

end;

do _n_ =

output;

end;

Thanks **data_null_** for your input. As always, a very smart suggested solution. As far as I know warning messages are generated becasue proc stdize uses location and scale parmaters to standardize/impute missing values. These statisticas are computed whatever is available within a variable. If all of the values are missing withing a variable/group then it will not be possible to calculate these statistics so as a result these messages are appearing in the log. I am not sure how to get rid of those and looking forward to have some suggestions from the forum regarding this.

I really like "all things STDIZE" but I don't want those warnings.
