TikZ 中的一些修改：在图片右侧插入文本/数学

按照问题和答案这个问题

我尝试根据自己的需要修改代码。虽然仍然有问题，但我还是成功了。我的代码是：

\documentclass{beamer}
\usepackage{tikz}
\usetikzlibrary{arrows,calc,positioning,quotes}

\tikzset{
  block/.style={
    rectangle,
    draw,
    minimum width=5em,
    rounded corners,
    minimum height=6ex
  },
  line/.style={draw, -latex'},
}

\begin{document}
\begin{frame}{Instrumental variables}
\begin{columns}
    \begin{column}{.48\linewidth}
\begin{tikzpicture}[node distance=1cm and 2.5cm]
    \node [block] (x) {$x$};
    \pause[2]
    \node [block, right=of x] (y) {$y$};
    \pause[3]
    \node [block, above=2cm of {$(x)!0.5!(y)$}] (z) {$z$};
\pause[4]
\draw[line] (z) edge ["instrument" '] (x) 
                (x) edge["instrumented" '] (y);
\end{tikzpicture}
    \end{column}
    \hfill
    \begin{column}{.44\linewidth}
\begin{itemize}
\item   $z$ is an instrument for $x$;\medskip
\item   $x$ is an instrumented regressor for $y$;\medskip
\item   The idea is that:\medskip
\begin{itemize}
\item $E\left( x|\varepsilon \right) \neq 0$\medskip
\item $E\left( z|\varepsilon \right) =0$\medskip
\item $E\left( z|y \right) = 0$\medskip 
\end{itemize}
\end{itemize}
    \end{column}
\end{columns}
\end{frame}
\end{document}

我喜欢按顺序显示图表。只有在显示完整图片后，我才想在 RHS 上显示文本。我尝试写\pause[5]在第二列开始之前写入，但它不起作用。

有人能帮助我吗？

像这样吗？

\documentclass{beamer}
\usepackage{tikz}
\usetikzlibrary{arrows,calc,positioning,quotes}

\tikzset{
  block/.style={
    rectangle,
    draw,
    minimum width=5em,
    rounded corners,
    minimum height=6ex
  },
  line/.style={draw, -latex'},
}

\begin{document}
\begin{frame}{Instrumental variables}
\begin{columns}
    \begin{column}{.48\linewidth}
\begin{tikzpicture}[node distance=1cm and 2.5cm]
    \node [block] (x) {$x$};
\uncover<2->{
    \node [block, right=of x] (y) {$y$};
            }
\uncover<3->{
    \node [block, above=2cm of {$(x)!0.5!(y)$}] (z) {$z$};
            }
\uncover<4->{
    \draw[line] (z) edge ["instrument" '] (x)
                (x) edge["instrumented" '] (y);
            }
\end{tikzpicture}
    \end{column}
    \hfill
    \begin{column}{.44\linewidth}
\uncover<5->{
\begin{itemize}
\item   $z$ is an instrument for $x$;\medskip
\item   $x$ is an instrumented regressor for $y$;\medskip
\item   The idea is that:\medskip
\begin{itemize}
\item $E\left( x|\varepsilon \right) \neq 0$\medskip
\item $E\left( z|\varepsilon \right) =0$\medskip
\item $E\left( z|y \right) = 0$\medskip
\end{itemize}
\end{itemize}
    }
    \end{column}
\end{columns}
\end{frame}
\end{document}

附录： 关于下面的评论，看看 MWE 的这种重新排列是否可以帮助您设计真正的透明胶片......

\documentclass{beamer}
\usepackage{tikz}
\usetikzlibrary{arrows,calc,positioning,quotes}

\tikzset{
  block/.style={
    rectangle,
    draw,
    minimum width=17mm,
    rounded corners,
    minimum height=9mm,
    font=\Large
  },
  line/.style={draw, -latex'},
}

\begin{document}
\begin{frame}{Instrumental variables}
\begin{columns}
    \begin{column}{.48\linewidth}
\begin{tikzpicture}[node distance=1cm and 0.5cm]
\uncover<2->{
    \node [block] (z) {$z$};
            }
\uncover<3->{
    \node [block, below left=of z]  (x) {$y$};
    \draw[line] (z) edge ["instrument" '] (x);
            }
\uncover<4->{
    \node [block, below right=of z] (y) {$y$};
    \draw[line] (x) edge["instrumented" '] (y);
            }
\end{tikzpicture}
    \end{column}
    \hfill
    \begin{column}{.48\linewidth}
\uncover<5->{
\begin{itemize}
\item   $z$ is an instrument for $x$;\medskip
\item   $x$ is an instrumented regressor for $y$;\medskip
\item   The idea is that:\medskip
\begin{itemize}
\item $E\left( x|\varepsilon \right) \neq 0$\medskip
\item $E\left( z|\varepsilon \right) =0$\medskip
\item $E\left( z|y \right) = 0$\medskip
\end{itemize}
\end{itemize}
    }
    \end{column}
\end{columns}
\end{frame}
\end{document}
