Daniel,
You need to check: ipolate and impute for improper imputation (averaging), and ice and hotdeck for proper imputation (use findit to download them).

Asunto: st: FW: Imputation Commands ?
Hi Statalisters,
I'm having trouble finding the proper command to impute values in a given row of data. Hoping someone could direct me appropriately.
Consider a row of data as follows
��������� obs x1� x2� x3� x4 x5
��������� --�� --� --� --� --� -- --
��������� 1�� 2�� 4�� .��� 5� 1
��������� 2�� .�� 4�� 1��� 3� 0
��������� 3�� 1�� .�� .�� � .� 1
What I want to do is to fill-in the missing values as a function of the surrounding row/variable values. I presume I want to average a given missing-value's surrounding +-3 values and impute accordingly.
What command or commands should I investigate?
Thank you for your time,
Best regards ---
