It is not clear that these statistics are meaningful for a nonlinear regression model. 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.
