WebSep 5, 2024 · In this section we compare the answers to the two main questions in differential equations for linear and nonlinear first order differential equations. Recall that for a first order linear differential equation. (2.9.2) y = e − ∫ p ( x) d x ∫ g ( x) e ∫ p ( x) d x d x + C (2.9.3) = 1 m ∫ g ( x) m d x + C. WebIf a regression equation doesn’t follow the rules for a linear model, then it must be a nonlinear model. It’s that simple! A nonlinear model is literally not linear. The added flexibility opens the door to a huge number of possible forms. Consequently, nonlinear regression can fit an enormous variety of curves.
