Hi All,

I get the following error message. It happens after computing the mode and before launching the MCMC. For some choice of priors it does not occur. Does anybody know what this might mean?

Thanks,

Mariano

??? MYDGGES requires two square real matrices of the same dimension.

Most likely there was a problem at the mode computation stage and the values passed to MCMC aren’t a good initial point.  
Can you upload the \*.mod file and the data so that we can get a closer look?

Best

Michel

Thanks Michel! Please find attached the data and \*.mod file.
