Dear all,

I receive the following error from realcomImputeLoad. Stata is set to the correct directory containing the impvals and imputeiter files and these seem fine - I've retrieved them and successfully imputed models in MLwiN.

The error (from a couple of lines before it in the traced output) is below. I've copied the output to the end to help colleagues identify where the error is coming in.

I'd very much appreciate any feedback,

Best wishes and thanks for your continuing support

Jamie

The only reshape command that I can find in realcomImputeLoad.ado is: This would match with the error message that you are getting as this refers to a variable starting with v.

I would firstly suggest that you look to see whether there is anything obviously wrong with the input file by running the command: and checking the imported data. The fourth record should contain a line of filenames, one for each imputed dataset.

If it all looks okay then you can ensure that all the variables are the same type by adding the following code just before the reshape line in realcomImputeLoad.ado:

Dear Chris,

Many thanks again for your support. I identified the problem - v11 was full of missing values - the impval file had some white space after the list of filenames (so a bit hard to spot what was up with it!)

Data now into Stata.

Best wishes and thanks again,

Jamie
