Fitting lines to points in the plane
Abstract
We seek for lines of minimal distance to finitely many points in the plane. The distance between a line and a set of points is defined by the Lp-norm, 1≤ p≤ ∞, of the vector of vertical or orthogonal distances from the single points to the line. The known properties of optimal lines are deduced by elementary considerations and represented using a uniform language for the different choices to define the distance from a line to a set of points.
