How to split item in itemize over two lines

Question

I have to use the document set up with the packages shown because this is dictated by the journal.

I simply want to prevent the item shown below from disappearing off the right hand side of the page. The most obvious solution would be to split it over two lines.

%The following LaTeX file is an example of an acceptable paper for the 
%Communications in Statistics.

%cisform.tex

\setlength\tabcolsep{5.69pt} % distance between columns in table


\begin{document}


\begin{itemize}
    \item  Simulate the X variables using eqn.1 with the following $(\rho_1,\rho_2)=(0.99,0.99),(0.99,0.1),(0.9,0.9),(0.9,0.1),(0.7,0.3)$
\end{itemize}

Answer 1

Two ways, \\ and parbox.

The default \parbox command centers the box, and thus the bullet point, but by specifying [t] like \parbox[t]{\linewidth}{<content>} the box is aligned according to the top line and the bullet point works properly.

\begin{document}
\begin{itemize}
    % you could use a simple \\ to manually break the line
    \item  Simulate the X variables using eqn.1 with the following \\$(\rho_1,\rho_2)=(0.99,0.99),(0.99,0.1),(0.9,0.9),(0.9,0.1),(0.7,0.3)$
    % or use a top-aligned parbox set to the linewidth to wrap it automatically
    \item \parbox[t]{\linewidth}{Simulate the X variables using eqn.1 with the following $(\rho_1,\rho_2)=(0.99,0.99),$ $(0.99,0.1),$ $(0.9,0.9),$ $(0.9,0.1),$ $(0.7,0.3)$}
    % I broke the long equation into smaller equations to make text-wrapping work right. 
\end{itemize}
\end{document}

Answer 2

Just split the thing into several formulas:

\documentclass[12pt]{article}

\begin{document}

\begin{itemize}
\item Simulate the $X$ variables using equation~\ref{whatever} with the following
$(\rho_1,\rho_2)=(0.99,0.99)$, $(0.99,0.1)$, $(0.9,0.9)$, $(0.9,0.1)$, $(0.7,0.3)$
\end{itemize}

\end{document}

Answer 3

I would make math into a displayed equation

\begin{itemize}
    \item  Simulate the X variables using eqn.1 with the following 
           \[(\rho_1,\rho_2)=(0.99,0.99),(0.99,0.1),(0.9,0.9),(0.9,0.1),(0.7,0.3)\]
\end{itemize}
