Required information Linear regression provides a powerful technique for fitting a best line to data. The below figure shows the transformations can be used to express the data in a form that is compatible with linear regression. Apart from the given figure, there are other models that can be linearized using transformations. For example, the following model applies to third-order chemical reactions in batch...
