ρ_{x y} = \frac{C o v (x, y)}{\sqrt{V (x) V (y)}} = \frac{E ((x - E (x)) (y - E (y)))}{\sqrt{E (x - E (x))^{2} E (y - E (y))^{2}}}

MathML rendered with MathJax

ρ_{x y} = \frac{C o v (x, y)}{\sqrt{V (x) V (y)}} = \frac{E ((x - E (x)) (y - E (y)))}{\sqrt{E (x - E (x))^{2} E (y - E (y))^{2}}}

\[ {\rho }_{xy}=\frac{\mr{Cov}(x,y)}{\sqrt {\mr{V}(x) \mr{V}(y)}} = \frac{\mr{E}(\, (x - \mr{E} (x)) (y - \mr{E} (y))\, )}{\sqrt {\mr{E}(x-\mr{E}(x))^{2}\, \mr{E}(y-\mr{E}(y))^{2}}} \]
