Does anyone know how you would type this in latex?
Thank you!
The amsmath package is the go-to for typesetting maths in LaTeX. I would suggest reading an online tutorial to get a grasp of the basics - the Mathematics page on the Wikibook and the overleaf tutorial are good places to start.
As for the expression, a simple trick to produce a curly brace spanning several lines is to put those lines in an array and surround the array with the delimiters \left\{ and \right. (the first prints the brace, the second nothing):
\documentclass{article}
\usepackage{amsmath} % Typsetting math in LaTeX
\begin{document}
\begin{equation*} % Unumbered equation environment for displayed math.
\frac{GHQ_{T+2}}{GHQ_{\text{baselevel}}} % Fraction; note \text{} command for baselevel text
= \left\{ % left deliminter
\begin{array}{l} % Array with a single, Left-justified column
> 1.15\\
0.85 \leq 1.5\\
<0.85\\
\end{array}
\right. % right deliminter (required)
\end{equation*}
\end{document}
Output:
cases environment is probably better (see the duplicate for an example).
