The Correlation Coefficient: An Overview
TL;DR: This paper discusses the uses of the correlation coefficient r, either as a way to infer correlation, or to test linearity, and recommends the use of z Fisher transformation instead of r values because r is not normally distributed but z is (at least in approximation).
