Hello I need one urgent help I am trying to fit the Sigmod curve of logistic growth model using NLS estimation. But i do not get the R square value in that even after getting the "Summary" In that case how to compare the fit for 3 models and find which one is better fit?? How to get this R Square value when using NLS estimation? Thanks Ruchita [[alternative HTML version deleted]]
