Subject: coefficient of determination on a nls regression
Hello R-users,
How can I caculate the coefficient of determination (r-squared, r2) from a
nls regression model?
r2 = regression SS / total SS
The regression SS is given by deviance(model), isn't it? And what about
total SSQ?
Thanks,
Antonio Olinto
