The correlation coefficient is symmetrical with respect to XX and YY, i.e. rXY=rYXrXY=rYX
The correlation coefficient is the geometric mean of the two regression coefficients r=bYX×bXY−−−−−−−−√r=bYX×bXY or r=b×d−−−−√r=b×d.
The correlation coefficient is independent of origin and unit of measurement, i.e. rXY=rUVrXY=rUV.
