How to fill out non-linear least-squares minimization

How to fill out non-linear least-squares minimization

1. To fill out non-linear least-squares minimization, follow these steps:
2. - Determine the objective function to be minimized. This function should depend on the parameters that need to be estimated.
3. - Define the initial parameter values. These values will serve as starting points for the optimization process.
4. - Choose an optimization algorithm. There are various algorithms available, such as Levenberg-Marquardt or Gauss-Newton, that can be used for non-linear least-squares minimization.
5. - Implement the optimization algorithm using a programming language or a dedicated software package.
6. - Provide the data that needs to be fitted to the model. This data should contain the dependent variable values and the corresponding independent variable values.
7. - Run the optimization algorithm on the provided data and initial parameter values.
8. - Monitor the convergence of the algorithm. It may be necessary to adjust the algorithm parameters or change the initial parameter values if the convergence is not satisfactory.
9. - Once the algorithm converges, retrieve the estimated parameter values.
10. - Analyze the results and assess the goodness of fit. This can be done by evaluating statistical measures, such as the sum of squared residuals or the coefficient of determination.
