WebAs is common in statistical literature, the term goodness of fit is used here in several senses: A “good fit” might be a model that your data could reasonably have come from, given the assumptions of least-squares fitting in which the model coefficients can be estimated with little uncertainty WebNov 6, 2024 · ft = fittype (@ (a1,a2,b1,b2,b3,x) 1.21+ (a1+a2.*T1).*x+s.*log ( (b1+b2./T1+b3./T1.^2).*x+1), 'independent', 'x'); Here I created an anonymous function in the call.
