Imputation error:

Hi all,

Trying to run my imputation through realcom and came across a flurry of errors (see below). Not sure where to begin with these and wondered if you could share any insights into why this may be happening?

I have a text file specified using the realcomImpute package in Stata and have followed all the instructions in the help file in regards to its specification. Looks as if something isn't balancing in regards to the matrices, but can't quite understand why this is?

Any help appreciated.

I can't tell if the image successfully attached so the text form is below:

iteration 10
iteration 20
iteration 30
iteration 40
Error using +
Matrix dimensions must agree.

I'm not sure what might be causing this, although as this happens after some successful iterations have occurred it suggests that something may be going wrong with the fitting. Are you able to provide more information regarding the model specification? You could try reducing the iterations to be lower than the number that ran successfully so that you can at least look at what kind of parameter values are being produced so far.
