Nettet(c) The same data from (a) are shown with a fitted linear regression line (blue dashed line) from peak-to-trough (shaded region). The red line depicts the running average across all observers. NettetAbbildung 1: Data with errors in both variables. The goal is to nd a straight line t taking the errors in both variables into account. For this data, ˙ x = 0:5 and ˙ y = 0:8 are known. Using the linear relation between the x i and the y i gives Nequations, but two additional parameters, leading to a net reduction of the number of unknown ...

If you are doubtful about the relevance of a variable, and it is also likely to be difficult to measure precisely, you may be doing your regression model a favor by …
