NettetNonlinear Regression Calculator. If 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. Let's assume a quadratic model function: Y = a * X^2 + b * X + c. References: Fit a non-linear regression with LevenbergMarquardt . Paste Y here. Nettet2. des. 2024 · The simple regression linear model represents a straight line meaning y is a function of x. When we have an extra dimension (z), the straight line becomes a plane. Here, the plane is the function that expresses y as a function of x and z. The linear regression equation can now be expressed as: y = m1.x + m2.z+ c
