Table extending beyond the page width

Question

I know there are a few posts with similar titles. But my case is different. When I use \documentclass{article}, my table fits properly on the page. But when I use my university's document class \documentclass{ucr}, my table becomes stretched and goes beyond the page width.

The code that works:

\documentclass[12pt]{article}
%\usepackage[top=1in, left=1in, right=1in, bottom=1in]{geometry}
\usepackage{amsmath}
\usepackage{graphicx}
\usepackage{array}
\usepackage{booktabs}

\begin{document}
\begin{table}[!h]
\centering{}%
\begin{tabular}{>{\centering}p{2cm}>{\centering}p{2cm}>{\centering}p{2cm}}
\toprule 
\centering{}Parameters & \centering{}GARCH-N & \centering{}GARCH-t\tabularnewline
\midrule
\midrule 
$\delta$ & \centering{}0.1106{*} (6.50)  & \centering{}.1084{*} (6.1425) \tabularnewline
$\beta_{1}$ & \centering{}0.630{*} (9.64)  & \centering{}0.629{*} (9.031) \tabularnewline
$\alpha_{0}$ & \centering{}0.008{*} (2.86)  & \centering{}0.008{*} (2.855) \tabularnewline
$\alpha_{1}$ & \centering{}0.203{*} (4.15)  & \centering{}0.232{*} (4.412) \tabularnewline
$\alpha_{2}$ & \centering{}0.663{*} (10.34)  & \centering{}0.639{*} (9.261) \tabularnewline
$\text{\ensuremath{\nu}}$ &  & \centering{}5.51{*} (63.53) \tabularnewline
Log- Likelihood & 14.603 & 26.318\tabularnewline
\bottomrule
\end{tabular}
%\begin{doublespace}
\caption{Blah blah}
%\end{doublespace}
\end{table}
\end{document} 

The code that does not work is the same as the above except the first line:

\documentclass[12pt]{ucr}

You can download the ucr class file called LaTex Template (Chairperson)* from http://graduate.ucr.edu/filingresources.html

I will be grateful if you could provide some suggestions here.

Answer 1

First off, whatever else you do, delete (or comment out) the penultimate line in ucr.cls, viz., the instruction \dsp. It is simply unconscionable to impose triple-spacing. (That final \dsp directive comes on top of other commands that increase line-spacing as well! Yikes!!)

Second, you're definitely abusing the p column type. (The ucr document class does a separate "job" on the p column type...) It would be much better if you placed the standard errors on separate lines and used a basic c column type for columns 2 and 3. (And, use the l ("left") column type, not c or p, for the first column.) Even better, load the dcolumn package and align the numbers in columns 2 and 3 on their decimal markers; see the following code for an application.

Do get rid of all \centering{} directives, and please replace $\text{\ensuremath{\nu}}$ with $\nu$. The less code clutter, the better.

\documentclass[12pt]{ucr-mod}   % modified by commenting out the final `\dsp` directive
\usepackage{amsmath,graphicx,array,booktabs}
\usepackage{dcolumn}
\newcolumntype{d}[1]{D..{#1}}
\newcommand\mc[1]{\multicolumn{1}{c}{#1}} % handy shortcut macro

\begin{document}
\setcounter{chapter}{1} % just for this example

\begin{table}[!h]
\centering
\begin{tabular}{ l d{3.5} d{3.5} }
