How would this be done in LaTeX? […]

Two possible packages.

• PGF/TikZ (Example Gallery)
• PSTricks (Example Gallery)

With this information you can start on your own and present code for corrections if necessary.

Here's what I've got.

Code: Select all

\documentclass[12pt]{article}
\usepackage[margin=2cm]{geometry}
\usepackage{tikz}
\usetikzlibrary{positioning}
\usetikzlibrary{arrows}
\usetikzlibrary{shapes.multipart}

\begin{document}
\begin{center}
%\begin{tikzpicture}[every text node part/.style={align=center}] used for multiple parts,
%along with shapes.multipart tikz library.
\begin{tikzpicture}[sharp corners=2pt,inner sep=7pt,node distance=.8cm,every text node part/.style={align=center}]

% Draw rectangular nodes (switch sharp to smooth for different corners)
\node[draw, minimum height = 4cm, minimum width = 4cm] (state0){\textbf{0} \\ \\
$(x)$ and $(y)$ \\ both alive};
\node[draw,below=2cm of state0, minimum height = 4cm, minimum width = 4cm](state2){\textbf{2} \\ \\
Only $(y)$ is alive};
\node[draw,right=2cm of state0, minimum height = 4cm, minimum width = 4cm](state1){\textbf{1} \\ \\ 
Only $(x)$ is alive};
\node[draw,below=2cm of state1, minimum height = 4cm, minimum width = 4cm](state3){\textbf{3} \\ \\
$(x)$ and $(y)$ \\  both dead};

%Draw arrows
\draw[-triangle 60] (state0) -- (state2) node [midway, above, left = 0.1cm]{$\mu^{02}_{x+t:y+t}$};
\draw[-triangle 60] (state0) -- (state1) node [midway, above]{$\mu^{01}_{x+t:y+t}$};
\draw[-triangle 60] (state1) -- (state3) node [midway, above, right = 0.1cm]{$\mu^{13}_{x+t:y+t}$};
\draw[-triangle 60] (state2) -- (state3) node [midway, above]{$\mu^{23}_{x+t:y+t}$};
\draw[-triangle 60] (state0) -- (state3) node [midway, above, rotate = -45]{$\mu^{03}_{x+t:y+t}$};
\end{tikzpicture}
\end{center}
\end{document}

Is there any way I can guarantee that the shapes are squares with some length and width? (i.e., can I control the length and width of the squares without "minimum height" and "minimum width"?)

Yes. And you already do so successfully. Hence I don't see the problem. What exactly is the questions here?

[clarinetist]

What I mean is, is there a way for me to specify the dimensions of the nodes without the "minimum" parameters? For example, if I switched the dimensions to 3cm (code is below), the squares are no longer the same size.

\node[draw, minimum height = 3cm, minimum width = 3cm] (state0){\textbf{0} \\ \\

\node[draw,below=2cm of state0, minimum height = 3cm, minimum width = 3cm](state2){\textbf{2} \\ \\

I think the 4cm minimum is perhaps a bit too big for the page I'm putting it in. Is it because the text will not fit in the node?

The size of a node primarily orientates itself towards the size of its content. If the content is small, the minimum size specifications are active (by the keys minimum size, minimum width, minimum height). If the content is bigger than the specified minimum dimensions, the concerned node will grow and so it can happen that nodes have different sizes.
