GD&T Reference & Training … WebCurve Fitting with Log Functions in Linear Regression. A log transformation allows linear models to fit curves that are otherwise possible only with nonlinear regression. For instance, you can express the nonlinear function: Y=e B0 X 1B1 X 2B2. In the linear form: Ln Y = B 0 + B 1 lnX 1 + B 2 lnX 2.

However, if you transformed your x-axis on the log scale, then the displayed line would be straight.
