Fit ode to data mathematica
WebMar 28, 2016 · I have a system of ODEs that contains 3 unknown parameters that have to be optimised in order to fit the system to a given data set. This is the system of ODEs … Webfit = NonlinearModelFit [transformedData1, model [β, γ] [i, t], {β, γ}, {i, t}] This yields. FittedModel [model [-2.85412.x 10^6,0.0196833]] Since it is the well known SIR model, the parameter $\beta$ should be positive but I do not know why it gives a negative number. How can I fit the data to the ODE system and check if the differential ...
