Category:Lines of Best Fit

This category contains results about Lines of Best Fit.
Definitions specific to this category can be found in Definitions/Lines of Best Fit.

Let $S$ be a set of $n$ points on a cartesian plane:

$S = \set {\tuple {x_1, y_1}, \tuple {x_2, y_2}, \ldots, \tuple {x_n, y_n} }$

A line of best fit for $S$ is a straight line $\LL$, conveniently expressed in the slope-intercept form as $y = m x + c$, which minimizes the distances between the elements of $S$ and $\LL$ according to a particular criterion.
