The fitted line plot below illustrates the problem of using a linear relationship to fit a curved relationship. The R-squaredis high, but the model is clearly inadequate. You need to do curve fitting! When you have one independent variable, it’s easy to see the curvature using a fitted line plot. However, with multiple … See more Despite its name, you can fit curves using linear regression. The most common method is to include polynomial terms in the linear model. … See more When your dependent variable descends to a floor or ascends to a ceiling (i.e., approaches an asymptote), you can try curve fitting using a reciprocal of an independent variable … See more Nonlinear regression is a very powerful alternative to linear regression.
