I'm using \hat in my regression equation, but it doesn't look too good the way it is. Any tips?
Here's the code:
\documentclass[twocolumn]{article}
\usepackage{booktabs, makecell, tabularx}
\renewcommand\theadfont{\normalsize}
\renewcommand\theadgape{}
\setcellgapes{2pt}
\newcolumntype{L}{>{\raggedright\arraybackslash}X}
\usepackage{caption}
\usepackage{textcomp}
\usepackage{graphicx}
\raggedbottom
\usepackage{geometry}
\usepackage{rotating}
\usepackage{booktabs, makecell}
\usepackage[referable]{threeparttablex}
\usepackage{siunitx}
\usepackage[skip=1ex]{caption}
\usepackage{upquote}
\title{\LARGE \bf ECON 425 Term Paper}
\begin{document}
\hat{CEO Salary}
\end{document}
Any tips? Thanks!


\widehat. I do not know where you want to insert \hat. On the whole word or on the letter S? Here there is an excellent answer https://tex.stackexchange.com/questions/100574/really-wide-hat-symbol. – Sebastiano May 01 '18 at 20:14\hatis supposed to be for one letter only. Try\widehatas Sebastiano said. But it will stretch up to 3 letter or so at max. For more than that see https://tex.stackexchange.com/a/101136/134574 – Phelype Oleinik May 01 '18 at 20:15CEO Salaryas a variable, but some single symbol/letter, perhaps with an index, and tell the people that, e.g.$\xi$ is the CEO's salary.– Skillmon May 01 '18 at 20:16
