9.4 Nonlinear Regression In a nonlinear regression model, the derivatives are dependent on one or more parameters as in the following equation: (9.4)y=β0+β12xas∂y∂β1=2β1. We can determine that the above regression model is nonlinear. From this, it is clear that the model is ...
The most fundamental assumption of the nonlinear regression model is that for each observation the regressors are independent of the error term. If this assumption is not satisfied, the consistency of least squares estimators and robust M-estimators breaks down. Only in the linear case the ...
A ‘low-order’ regression analysis in modal space is then carried out using the classical RFS method (Masri et al., 1982 [134]; Al-Hadid and Wright, 1989 [138]). Experimental validation of the method using a single-bay panel structure and a wing-store structure is available in (...
Nonlinear regression is a statistical technique that helps describe nonlinear relationships in experimental data. Nonlinear regression models are generally assumed to be parametric, where the model is described as a nonlinear equation. Typically machine learning methods are used for non-parametric nonlinear...

regression models, while they typically form a straight line, can also form curves, depending on the form of the linear regression equation. Likewise, it’s possible to use algebra to transform a nonlinear equation so that it mimics a linear equation—such a nonlinear equation is referred to ...
