Can anyone help me in writing the following long expression with in IEEEeqnarray or eqnarray structure?
\documentclass[10pt,a4paper]{article}
\pagestyle{plain}
\usepackage{amsmath}
\usepackage{amsthm}
\usepackage{bm}
\usepackage{IEEEtrantools}
\begin{document}
\begin{IEEEeqnarray*}{rCl}
\Sigma^{*}(\hat{\bm{\beta}}^{S+})&=&E\left[\lim_{n\rightarrow\infty}\sqrt{n}(\hat{\bm{\beta}}^{S+}-\bm{\beta})\sqrt{n}(\hat{\bm{\beta}}^{S+}-\bm{\beta})^{'}\right]\\
&=&E\left[\lim_{n\rightarrow\infty}\sqrt{n}\left\{\hat{\bm{\beta}}^{S}-\left(1-(p_{2}-2)D^{-1}_{n}\right)I(D_{2}<p_{2}-2)(\hat{\bm{\beta}}-\tilde{\bm{\beta}})-\bm{\beta}\right\}\right]\\
&& \times \>
\end{IEEEeqnarray*}
\end{document}
Best Answer
This should let you start.
Use the
aligned
environment to get the equation split in two lines.MWE
EDIT
Since your request of making two consecutive lines, here it is, but notice that I've simply copied the previous one, not certainly typeset the formula in the image.... Replace that with your equation.
