Dear imputers
I have almost finished developing a web site on survey analysis as part of an ESRC (UK soc sci res council) research methods program. It is mainly about things like weighting and stratification, but since imputation is an important aspect I thought I should include an exemplar on this. I now rather regret this, since it has taken me months because the example data set, kindly provided by the researchers, was a real bummer to impute. I hope I have got it at least nearly right, but I would appreciate feedback on any aspects. The site is http://www.napier.ac.uk/depts/fhls/peas <http://www.napier.ac.uk/depts/fhls/peas/index.asp> and the two main bits relevant to imputation are http://www.napier.ac.uk/depts/fhls/peas/imputation.asp and http://www.napier.ac.uk/depts/fhls/peas/exemplar6.asp I would be most grateful for any feedback.

You might consider adding a link the the R/S-Plus aregImpute function, e.g. http://biostat.mc.vanderbilt.edu/s/Hmisc/html/aregImpute.html We have a paper under review comparing aregImpute with MICE (it compares quite favorably but is much faster and allows for nonlinear imputation models). -- Frank E Harrell Jr Professor and Chair School of Medicine Department of Biostatistics Vanderbilt University
