Nonlinear estimation

Nonlinear estimation is a method used to determine the values of unknown variables when the relationship between variables isn't a straight line or simple curve. Unlike linear estimation, where equations are straightforward, nonlinear estimation deals with more complex equations that can't be easily solved with simple methods. It involves using algorithms to iteratively adjust guesses until the model fits the observed data well. This approach is essential in situations where relationships are complicated, such as in economics, engineering, or science, helping us make accurate predictions or understand underlying processes despite the complexity.
