# Enumerate with different first line?

I want to do an enumeration, but the first line should be bolded, see e.g. this picture:

What is blue I want to have in bold. In addition, I don't know how to generate a new line for the other text in the enumerate environment, should I just use \\ ?

Use \textbf{...} around text that you want to embolden and \\ to break a line.

\documentclass{article}
\usepackage{enumerate}
\begin{document}
\begin{enumerate}[\bfseries1.]
\item \textbf{Specify a mean equation for the returns}\\
by testing for serial dependence of $r_t$ an, if necessary, building an ARMA model
\item \textbf{Test for ARCH Effects}\\
using the residuals of the mean equation
\item \textbf{Specify a volatility model} (if necessary)
\item \textbf{Estimate the complete model}\\
via joint estimation of mean an volatility parameters
\item \textbf{Check the fitted model}\\
and refine if necessary.
\end{enumerate}
\end{document}


For more automation, you may want to define a new command \bitem, as follows:

\documentclass{article}

\newcommand\bitem[1]{\item{\bfseries #1}\\}

\begin{document}

\begin{enumerate}
\bitem {Specify a mean equation for the returns}
by testing for serial dependence of $r_t$ an, if necessary, building an ARMA model
\bitem {Test for ARCH Effects} using the residuals of the mean equation
\bitem {Specify a volatility model} (if necessary)
\bitem {Estimate the complete model}
via joint estimation of mean an volatility parameters
\bitem {Check the fitted model} and refine if necessary.
\end{enumerate}
\end{document}

• I'd use only one argument: \bitem{bold text} Whatever follows Apr 29, 2013 at 12:16
• You're right yet again :) Apr 29, 2013 at 12:19
