Is it possible for root to fit a data set to differential equations to determine their parameters?

[Kachanon]

Hi,

I have a set of ordinary differential equations and a set of data points. I would like to fit the data points to the differential equations in order to determine the values of the parameters of the equations? Will it be possible to do it on ROOT?

There is several fit examples which can help you:

As you have data points, TGraph might be the best object to hold them:
