## Latex

$$ 
\begin{aligned}

y_j \sim N(\theta_j , \sigma_j^2) \\

\sigma_j = \nu/\sqrt{n_j}   \\

\theta = \mu +\tau \times \eta \\

\eta \sim N(0,1) \\

\mu + \tau\times\eta = \theta \sim N(\mu , \tau^2)

\end{aligned}
$$

On Windows, rstudio renders the equations correctly:

But, when I Knit the file and open the HTML with chrome or ie the latex is not rendered correctly:

Is there a way to fix this?

Answer 1

In case someone else is encountering this problem, @YihuiXie was right. Removing the empty lines solves the problem:
