所以我用 Latex Beamer powerpoint 做这个演示。我有一张幻灯片看起来很乱，但我需要将方程式分成几列并放在一张幻灯片中。它看起来是这样的：
这是使用的代码：
\begin{frame}{Introducing bootstrap}
- Historical data Z to a risk estimate $\hat{\Psi}$ \\
\begin{columns}[c]
\column{0in}
$\theta \rightarrow Z$,\\
the real world
\column{0in}
$\hat{\theta}=g(Z)$\\
$\hat{\Psi}=\Psi(\hat{\theta})$\\
estimation
\column{0in}
and
\column{0in}
$\hat{\theta} \rightarrow \hat{Z}^{*}$\\
in the computer
\column{0in}
$\hat{\theta}^{*}=g(\hat{Z}^{*})$\\
$\hat{\Psi}^{*}=\Psi(\hat{\theta}^{*})$\\
estimation
\end{columns}
- The idea is to identify the distribution of $\hat{\Psi}^{*}$ given $\hat{\theta}$ with that of $\hat{\Psi}$ given $\theta$.
\end{frame}
有人知道如何让它看起来有序且美观吗？
谢谢

您可以在启动环境时使用选项t（顶部对齐），并且可以提供比列更正常的宽度。onlytextwidthcolumns0in
\documentclass{beamer}
\begin{document}
\begin{frame}{Introducing bootstrap}
- Historical data Z to a risk estimate $\hat{\Psi}$
\medskip
\begin{columns}[t,onlytextwidth]
\column{.2\textwidth}
$\theta \rightarrow Z$,\\
the real world
\column{.2\textwidth}
$\hat{\theta}=g(Z)$\\
$\hat{\Psi}=\Psi(\hat{\theta})$\\
estimation
\column{.1\textwidth}
and
\column{.2\textwidth}
$\hat{\theta} \rightarrow \hat{Z}^{*}$\\
in the computer
\column{.2\textwidth}
$\hat{\theta}^{*}=g(\hat{Z}^{*})$\\
$\hat{\Psi}^{*}=\Psi(\hat{\theta}^{*})$\\
estimation
\end{columns}
\bigskip
- The idea is to identify the distribution of $\hat{\Psi}^{*}$ given $\hat{\theta}$ with that of $\hat{\Psi}$ given $\theta$.
\end{frame}
\end{document}
