I like math.

$$x$$

$$y$$

$$n$$

$$\bar{x}$$

$$\bar{y}$$

$$d = \sqrt{x^2 + y^2}$$

$$d_{xy} = \sqrt{\sum_{i=1}^{n}(x_{i} - y_{i})^2}$$

Pearson Correlation of gene x and y:

$$r_{xy} = \frac{\sum(x_{i} - \bar{x})(y_{i} - \bar{y})}{\sqrt{\sum(x_{i} - \bar{x})^2}\sqrt{\sum(y_{i} - \bar{y})^2}}$$

Un-centered correlation coefficient:

$$r_{xy}^u = \frac{\sum{x_{i}y_{i}}}{\sqrt{\sum{x_{i}}^2}\sqrt{\sum{y_{i}}^2}}$$
