I am currently working on analytic constrained fitting using generalised Lagrange Multipliers. This method finds the saddle points of the model and therefore allows for analytical expressions for the parameters....

Some Exception subclasses should be defined for better Exception handling, and to give users useful errors.

Hi. I am trying to do a curve fitting for two data sets (sig11-lam1) and (sig22-lam2) simultaneously since they have similar parameters. Both sig11 and sig22 are functions of lam1...

Perform global sensitivity analysis of ODE system

1

Is there a way to perform a global sensitivity analysis of the parameters of a system of ordinary differential equations that was fitted to data using symfit?

Numba integration

If numba is installed, we should `@jit(nopython=True, fastmath=True)` compile the model when we lambdify them. This should of course be optional. If numba is not installed everything should work out...
