Existing fitting modules are not very pythonic in their API and can be difficult for humans to use. This project aims to marry the power of scipy.optimize with the readability of SymPy to create a highly readable and easy to use fitting package which works for projects of any scale.
symfit makes it extremely easy to provide guesses for your parameters and to bound them to a certain range:
a = Parameter(1.0, min=0.0, max=5.0)
To define models to fit to:
x = Variable() A = Parameter() sig = Parameter(1.0, min=0.0, max=5.0) x0 = Parameter(1.0, min=0.0) # Gaussian distrubution model = A * exp(-(x - x0)**2/(2 * sig**2))
To execute the fit:
fit = Fit(model, xdata, ydata) fit_result = fit.execute()
And finally, to evaluate the model using the best fit parameters:
y = model(x=xdata, **fit_result.params)
