In data modeling, multivariate nonlinear regression is a widely used algorithm for analyzing relationships between multiple variables. Compared to linear regression models, multivariate nonlinear regression can more accurately describe complex relationships between variables, such as nonlinear patterns. This modeling approach can be applied across various domains including finance, medicine, and social sciences to uncover interactions and influences among variables. From an implementation perspective, this typically involves defining appropriate nonlinear functions (such as polynomial, exponential, or logarithmic transformations) and using optimization methods like gradient descent or Levenberg-Marquardt algorithm to estimate parameters. Key functions in programming implementations often include curve fitting routines and statistical evaluation metrics to assess model performance.
