Having trouble fitting data using NonlinearModelFit
I'm trying to fit
data = {{2002, 45000}, {2004, 90000}, {2005, 120000}, {2013, 211000}};
to an exponential function a*Exp[b*x]+c but Mathematica returns FittedModel[0] when I use:
NonlinearModelFit … [data,a*Exp[b*x]+c,{a,b,c},x]
Any help would be gladly welcomed. …
