Hi All,
I'm having trouble getting NLME to calculate standard error for the mixed residual error model. Here is part of the Core Output that I am getting. The only paramater value need a limit would be stdev0 and I know of no way to change that limit. Is this a problem whenever I use the mixed or combined residual error model?
Kind regards, Jim
