AMELIA

AMELIA: A Program for Missing Data -- for Windows (self-extracting file; version: 2.1, 7/15/2003) or for GAUSS (zip file; version: 2.1, 7/15/2003; see what's new).

By James Honaker, Anne Joseph, Gary King, Kenneth Scheve, and Naunihal Singh.

Both versions implement the same key procedures described in Gary King, James Honaker, Anne Joseph, and Kenneth Scheve's "Analyzing Incomplete Political Science Data: An Alternative Algorithm for Multiple Imputation" (APSR, 2001). (Named by ISI's Essential Science Indicators as an Emerging Research Frontier Article for being most cited in the field.) The Windows version requires no commercial software but the Windows operating system, is menu-oriented, and includes some data input procedures not in the GAUSS version.

The GAUSS version requires the commercial program GAUSS, will run on any platform that runs GAUSS, is command-oriented, and has a few statistical options not in the Windows version. Both files come with PDF versions of the documentation; or you can read the documentation online. You may also be interested in an interactive video on Amelia, and Clarify, which will now automatically combine multiply imputed datasets. For procedures Clarify does not handle, see Ken Scheve's MI program (Version: 2.1).
