[Basta-users] interaction term throwing an error

[Fernando Colchero]

Hi Dave,

   I believe that this is a problem in BaSTA that has to do with the way it handles the parameter names for the interactions. Could you send me a subset of the data so I can pin it down and try to fix it?

   Best,

   Fernando

I then tried to add an interaction term in the MakeCovMat which created the required matrix, I then put this through DataCheck with no problem and through basta and the model runs without issue, calculates DIC but then gives the following error code and will not give me any output?
