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 ---
