aregImpute does not do what you want. It creates n.impute different values for each missing datum. You san see them with "imputed" in what it returns. You might be able to get what you want with some other package such as EMV, mix, norm, or the impute function in Hmisc. An excellent and discussion of imputation for the novice (which I just read yesterday - being a novice myself!) is by Shafer and Graham, in Psychological Methods, 2002, 7, 147-177. What aregImput does is shown in Fig. 4 of that paper, as I understand it. -- Jonathan Baron, Professor of Psychology, University of Pennsylvania Home page: http://www.sas.upenn.edu/~baron R page: http://finzi.psych.upenn.edu/ ______________________________________________ [EMAIL PROTECTED] mailing list https://www.stat.math.ethz.ch/mailman/listinfo/r-help
