I am preparing a presentation on statistics. I want to include a slide on Bayes' Theorem which says:
p(\theta | D) = \frac{p(D|\theta) p(\theta)} {p(D)}
I want to explain each term using arrows. How can I do this?
I tried to follow this example but my main problem is that I have a fraction. How can I split the fraction?
This is exactly what I want to do. Without the last line.
As cfr mentioned in her comment, better looking way is not to use footnote references for pictures. Try to put reference immediately below picture like this:
\begin{frame}
\includegraphics[width=\textwidth]{example-image}\\[-1ex]
{\tiny Source: \cite{foo12}}
\end{frame}
Edit:
An attempt to make command for stack of figure and citation of image source. For it I use package stackengine:
\documentclass{beamer}
\usepackage{stackengine}
\newcommand{\figcite}[3]{
\def\stackalignment{l}
\stackunder{\includegraphics[width=#1]{#2}}{\scriptsize Source: \cite{#3}}
}
\usepackage[style=verbose]{biblatex}
\usepackage{filecontents}% to embed the file `myreferences.bib` in your `.tex` file
\begin{filecontents*}{myreferences.bib}
@online{foo12,
year = {2012},
title = {footnote-reference-using-european-system},
url = {http://tex.stackexchange.com/questions/69716/footnote-reference-using-european-system},
}
\end{filecontents*}
% File is created and written to disk by the above package
\addbibresource{myreferences.bib}
\begin{document}
\begin{frame}
\figcite{\textwidth}{example-image}{foo12}
\end{frame}
\begin{frame}
\printbibliography
\end{frame}
\end{document}
If you want to add text to just one slide, try \only<>{}
\documentclass{beamer}
\begin{document}
\begin{frame}
Complete SM lagrangian can be written as-
\[\mathcal{L}_{SM}=\textcolor{blue}{i\overline{\psi}\gamma^{\mu}\mathcal{D}_{\mu}\psi}\only<1>{~\fbox{explain something}}\pause
\textcolor{red}{ -\frac{1}{4}G^{\mu\nu A}G_{\mu\nu}^{A}-\frac{1}{4}W^{\mu\nu I}W_{\mu\nu}^{I}-\frac{1}{4}B^{\mu\nu}B_{\mu\nu}}\]
\[\pause\textcolor{magenta}{+h_{ij}^{u}\overline{Q}_{i}U_{j} \widetilde{H}+h_{ij}^{d}\overline{Q}_{i} D_{j}H+h_{ij}^{e}\overline{L}_{i}E_{j}H+h.c.}\]
\pause
\begin{equation}
\textcolor{violet}{+(\mathcal{D}_{\mu}H)^{\dag}\mathcal{D}_{\mu}H-\mu^{2}H^{\dag}H+\lambda(H^{\dag}H)^{2}}
\end{equation}
\end{frame}
\end{document}
With a bit of help from https://tex.stackexchange.com/a/205623/36296 you could also explain the terms like this
\documentclass{beamer}
\usepackage{mathtools}
\newcommand<>{\uncoverubrace}[2]{%
\onslide#3 \underbrace{ \onslide<1->%
#1%
\onslide#3 }_{#2} \onslide<1->%
}
\newcommand<>{\uncoverobrace}[2]{%
\onslide#3 \overbrace{ \onslide<1->%
#1%
\onslide#3 }^{#2} \onslide<1->%
}
\begin{document}
\begin{frame}
Complete SM lagrangian can be written as-
\[\mathcal{L}_{SM}=\uncoverubrace<1>{\textcolor{blue}{i\overline{\psi}\gamma^{\mu}\mathcal{D}_{\mu}\psi}}{\only<1>{\fbox{matter}}}\pause
\textcolor{red}{ -\frac{1}{4}G^{\mu\nu A}G_{\mu\nu}^{A}-\frac{1}{4}W^{\mu\nu I}W_{\mu\nu}^{I}-\frac{1}{4}B^{\mu\nu}B_{\mu\nu}}\]
\[\pause\textcolor{magenta}{+h_{ij}^{u}\overline{Q}_{i}U_{j} \widetilde{H}+h_{ij}^{d}\overline{Q}_{i} D_{j}H+h_{ij}^{e}\overline{L}_{i}E_{j}H+h.c.}\]
\pause
\begin{equation}
\textcolor{violet}{+(\mathcal{D}_{\mu}H)^{\dag}\mathcal{D}_{\mu}H-\mu^{2}H^{\dag}H+\lambda(H^{\dag}H)^{2}}
\end{equation}
\end{frame}
\end{document}

You can use the
tikzmarklibrary; the idea is to place some marks at the desired locations and then to use those marks to have pointers for the explanations:An animation of the result:
