Math & Science ⇒ Automatically scaled Delimiters in multiline Equations

[gmgpina20]

Dear users, can you help me in introducing an equation in {eqnarray} environment? The equation in question is this.

\begin{eqnarray}\label{eq:verom}
  \mathcal{L}(\alpha,\Omega) &\propto&\left|\Omega   \otimes \mathbb{I}_{T}\right|^{-1/2}exp\left\{-\frac{1}{2}\left(\alpha-\alpha_{ols}\right)^{\prime}\left(\Omega^{-1}\otimes \mathbb{X}^{\prime}\mathbb{X}\right)\left(\alpha-\alpha_{ols}\right) \nonumber \\
  &-&\frac{1}{2}\left[\left(\Omega^{-1/2}\otimes \mathbb{I}_{T}\right)y-\left(\Omega^{-1/2}\otimes \mathbb{X}\right)\alpha_{ols}\right]^{\prime}\left[\left(\Omega^{-1/2}\otimes \mathbb{I}_{T}\right)y-\left(\Omega^{-1/2}\otimes \mathbb{X}\right)\alpha_{ols}\right]\right\}
\end{eqnarray}

When I run the file, I got some errors because \exp\left\{ \right\} is not recognized for separate equation. How can I open { in one line and close it again -}- in another line in {eqnarray} environment?

Thank you for you help.

Avoid eqnarray! Use the corresponding environments provided by amsmath (perhaps enhanced by mathtools from the mh bundle).

Regardless of that you can't split automatically scaled pairs of delimiters over several lines. Either use a closing invisible delimiter or manual delimiter scaling.
