Dear all , I would like to know if this is possible to calculate the goodness of fit measures R-square, adjusted R square, RMSE etc for an exponential fit without using curve fitting tool box.
When I do the exponential fit for my data , I get only the coefficient a and b exemple f =
General model Exp1:
f(x) = a*exp(b*x)
Coefficients (with 95% confidence bounds):
a = 0.4396 (0.3358, 0.5434)
b = -4.105e-05 (-0.001221, 0.001139)
Thanks in advance

AFAIK, no, it seems TMW has been careful to not do so to keep market for the Toolbox.
You might check on FileExchange for contributions; I don't know if they've prevented the facility to protect the market share there or not.
