NettetMay I use linear regressio to model non-linear functions? You may use the linear regression to model anything you want, this does not necessarily mean that the results will be a good fit. The mere decision to use a model makes no assumptions on whether the underlying equation is in fact reflected by the model you choose. Nettet3. jun. 2024 · Non-linear data is usually encountered in daily life. Consider some of the equations of motion as studied in physics. Projectile Motion: The height of a projectile is calculated as h = -½ gt 2 +ut +ho; Equation of motion under free fall: The distance travelled by an object after falling freely under gravity for ‘t’ seconds is ½ g t 2. ...
