Pivot Analysis in Weighted Linear Regression
School of Mathematics, University of Manchester, Manchester M13 9PL, UK
Abstract. According to Lutzer (2017), the simple linear regression lines based on repeating single observations from a given dataset pivot at a certain pivotal point. In this paper, we discuss this behavior in a more general case and give an explanation about the pivot behavior.
