For example, an R^2 value is meaningful when the model being fit contains the constant model because it compares the fit of the current model to the fit of the model y ~ 1. Not all nonlinear regression models contain the constant model as a submodel. ______________________________________________ R-help@r-project.org mailing list https://stat.ethz.ch/mailman/listinfo/r-help PLEASE do read the posting guide http://www.R-project.org/posting-guide.html and provide commented, minimal, self-contained, reproducible code.
