# Regression

Given a function $$f$$ and a set of values $$x_i$$, regression is the creation of a curve that approximates $$f$$ from a set of points $$\left(x_i, y_i\right)$$ where
$y_i = f\left(x_i\right) + \epsilon_i$
and $$\epsilon_i$$ are observations of some unknown random variables $$E_i$$, typically assumed to have means of zero and to be independent of each other.
