Least Square Method, Curve Fitting, Python, Residual, Data.
The Python code to fit the exponential function and show the fitted values are as follows: # Calculate the residuals residuals = y_data - model_func(x_data, *popt) # Plot the residuals plt.scatter(x_data, residuals) plt.axhline(0, color='red', linestyle='--') plt.xlabel('x') plt.ylabel('Residuals')
