The R-squared and nonlinear regression: a difficult marriage?

WebLinear Function. A linear function is a function that represents a straight line on the coordinate plane. For example, y = 3x - 2 represents a straight line on a coordinate plane and hence it represents a linear function. Since y can be replaced with f(x), this function can be written as f(x) = 3x - 2. WebThe log functions fit the linear model specification. I also show this in my discussion about log-log plots. As for the R-squared, if you can use a transformation in a linear model to fit an underlying nonlinear function, your software will give you an R-squared value.
