Further analysis of the maintenance status of symfit based on released PyPI versions cadence, the repository activity, and other data points determined that its maintenance is Inactive.

An important project maintenance signal to consider for symfit is that it hasn't seen any new versions released to PyPI in the past 12 months, and could be considered as a discontinued project, or that which receives low attention from its maintainers.

As a healthy sign for on-going project maintenance, we found that the GitHub repository had at least 1 pull request or issue interacted with by the community.

Project Goals

The goal of this project is simple: to make fitting in Python pythonic. What does pythonic fitting look like? Well, there's a simple test. If I can give you pieces of example code and don't have to use any additional words to explain what it does, it's pythonic.

from symfit import parameters, variables, Fit, Model
import numpy as np

xdata = np.array([1.0, 2.0, 3.0, 4.0, 5.0])
ydata = np.array([2.3, 3.3, 4.1, 5.5, 6.7])
yerr = np.array([0.1, 0.1, 0.1, 0.1, 0.1])

a, b = parameters('a, b')
x, y = variables('x, y')
model = Model({y: a * x + b})

fit = Fit(model, x=xdata, y=ydata, sigma_y=yerr)
fit_result = fit.execute()

Cool right? So now that we have done a fit, how do we use the results?

import matplotlib.pyplot as plt

yfit = model(x=xdata, **fit_result.params)[y]
plt.plot(xdata, yfit)
plt.show()

Need I say more? How about I let another code example do the talking?

from symfit import parameters, Fit, Equality, GreaterThan

x, y = parameters('x, y')
model = 2 * x * y + 2 * x - x**2 - 2 * y**2
constraints = [
    Equality(x**3, y),
    GreaterThan(y, 1),
]

fit = Fit(- model, constraints=constraints)
fit_result = fit.execute()

I know what you are thinking. "What if I need to fit to a system of Ordinary Differential Equations?"

from symfit import variables, Parameter, ODEModel, Fit, D
import numpy as np

tdata = np.array([10, 26, 44, 70, 120])
adata = 10e-4 * np.array([44, 34, 27, 20, 14])

a, b, t = variables('a, b, t')
k = Parameter('k', 0.1)

model_dict = {
    D(a, t): - k * a**2,
    D(b, t): k * a**2,
}

ode_model = ODEModel(model_dict, initial={t: 0.0, a: 54 * 10e-4, b: 0.0})

fit = Fit(ode_model, t=tdata, a=adata, b=None)
fit_result = fit.execute()
