![为什么 LaTeX 告诉我缺少 {?](https://linux22.com/image/286206/%E4%B8%BA%E4%BB%80%E4%B9%88%20LaTeX%20%E5%91%8A%E8%AF%89%E6%88%91%E7%BC%BA%E5%B0%91%20%7B%EF%BC%9F.png)
每当我编译包含以下代码的文档时,它都会在 pdf 上产生令人满意的输出,但却出现错误:
43
Missing { inserted.
<to be read again>
\gdef
l.43 \item $\mu_\hat{p}
$ = mean of all possible values of $\hat{p} = \pi$. \\
\begin{itemize}
\item $\mu_\hat{p}$ = mean of all possible values of $\hat{p} = \pi$. \\
\item $\sigma_\hat{p}$ = standard deviation of all possible values of \^p = $\sqrt{\frac{\pi(1-\pi)}{n}}$ \\
\item CLT (for \^p): If $n\pi \geq 10$ \underline{AND} $n(1-\pi) \geq to$, then the histogram of all possible values of \^p will be approximately normal. \\
\end{itemize}
我做错了什么?
答案1
下标需要用括号括起来:\mu_{\hat{p}}
和\sigma_{\hat{p}}
\documentclass{article}
\usepackage{amssymb}
\begin{document}
\begin{itemize}
\item $\mu_{\hat{p}}$ is the mean of all possible values of $\hat{p} = \pi$.
\item $\sigma_{\hat{p}}$ represents the standard deviation of all possible values of $\hat{p} = \sqrt{\frac{\pi(1-\pi)}{n}}$
\item CLT (for $\hat{p}$): If $n\pi \geq 10$ \underline{AND} $n(1-\pi) \geq to$, then the histogram of all possible values of $\hat{p}$ will be approximately normal.
\end{itemize}
\end{document}
为了保持一致性,我还将文本更改\^p
为数学,并在每个文本末尾隐藏了(这些会产生 undefull )。也许您指的是?\hat{p}
\\
\item
\hboxes
$n(1-\pi) \geq to$
$n(1-\pi) \geq t_{0}$
下划线不是一个很好的印刷特性,所以我建议你抑制它。
