Latex code for multivariate normal (Gaussian) density

Question

I want to write the p-dimensional normal density formula in latex. I am not getting it correct. Can I get the code?

Answer 1

You can try the following latex code for the multivariate Gaussian density. It has been tested on overleaf.

\begin{equation}\label{eq:multivariate_gaussian_pdf}
\begin{split}
\mathcal{N}  (x_i|\mu_k, \Sigma_k) = \frac{1}{(2\pi)^{(p/2)} |\Sigma_k|^{1/2}} \exp \left\{- \frac{1}{2} \left(x_i-\mu_k\right)^{'} \Sigma_k^{-1} \left(x_i-\mu_k \right)  \right\}
\end{split}    
\end{equation}

The above code produces the following formula:
