DIFFERENT METHODS OF LINEAR FIT IN R²

Wilhelm Kolaczia

Abstract

In the field of metrology it is common practice to approximate the results of a measurement by functions modelling physical facts. The most simple form of such an approximation is the linear fit. This article presents five different methods of linear fit in R² by working out the characteristic features of these methods like scale unit invariance. The author's intention is to be helpful in finding the most useful method from case to case.
