The correlation coefficient is symmetrical with respect to X and Yi.e.//rxy=ryx

The correlation coefficient is the geometric mean of the two regression coefficients.

r=√byx×bxy // 

The correlation coefficient is independent of origin and unit of measurement. The correlation coefficient lies between -1 and +1.
