Yes, The WRES tend to be first >0 and then <0. The fit to the IV data
alone is little better with the 2 comp Model. Unfortunately, this is not the
case with the IR and SR formulations. When all the data is pooled together
I opted for 1 cmp. Model. I don't think a mixture model would be of any
help. I will try the IPRED VS IWRES; but I still can't understand how an IV
gives the worst diagnostics.. Thanks
