What Does NLLS Stand For?

NLLS stands for Nonlinear Least Squares

Nonlinear Least Squares (NLLS) is a mathematical optimization technique used to minimize the sum of the squares of residuals in models where the relationship between variables is nonlinear. This method is commonly applied in statistical modeling and curve fitting, where the objective is to find the best-fitting parameters that minimize discrepancies between observed data and a theoretical model. NLLS is widely utilized in various fields, including engineering, physics, and economics, to solve complex problems that cannot be adequately addressed using linear approaches.
