# LaTeX in WordPress

As part of a recent post on ridge and lasso regression techniques in R I wanted to present two mathamatical formulas. I checked for WordPress plugins that used LaTeX, but I learned you have to migrate your blog from WordPress.com to WordPress.org and I didn’t want to have to deal with that. Turns out I don’t have to! WordPress itself supports many of the features of LaTeX. You simple write “$latex” before your math equation, use standard LaTeX syntax, and then close with another “$”. Just like in LaTeX itself!! Below are two example equations I presented in my post:

Ridge Regression: $\mathbf{\hat{\beta}^{ridge} = \displaystyle arg\min_{\beta}\sum^{n}_{i=1}(y_i-(\beta_0 + \beta^Tx_i))^2 + \lambda\|\beta\|_{2}^{2}}$

Lasso Regression: $\mathbf{\hat{\beta}^{lasso} = \displaystyle arg\min_{\beta}\sum^{n}_{i=1}(y_i-(\beta_0 + \beta^Tx_i))^2 + \lambda\|\beta\|_{1}}$
