Data fitting programming Math 371

Data fitting programming Math 371. Can we do better?. x. c*x-r. Use these estimated parameters to run the solution of the model (the initial point is the first data point in the data table) and compare with data points. I use ode23 here, you can use ode45 to obtain the same solution.

  1. Data fitting programmingMath 371

  2. Can we do better? x .

  3. c*x-r

  4. Use these estimated parameters to run the solution of the model(the initial point is the first data point in the data table)and compare with data points

  5. I use ode23 here, you can use ode45 to obtain the same solution

  6. The solution fits data reasonably well but not very well. Do we have a better method for parameter estimation and data fitting?

  7. The solution fits data reasonably well but not very well. Do we have a better method for parameter estimation and data fitting? YES!

  8. Direct Method Least-square data fitting

  9. Revisit L-V predator-prey model Use the least-square method to fit data and estimate parameter values directly

  10. You can use ode45 or other ODE solvers; use help files to check their differences

  11. Almost perfect data fitting!

  12. a b c r
