[Tex/LaTex] adding significance levels under regression result table

multicolumntables

I have a table as the following:

\begin{table}[htbp]\centering
\caption{Dependent Variable: Enrollment}
\begin{tabular}{c c c c}
\hline\hline 
\textbf{Variable} & \textbf{Model 1} & \textbf{Model 2} & \textbf{Model 3}\\ \hline
frl         &      -0.012   &      -0.052   &      -0.156** \\
            &      (0.04)   &      (0.06)   &      (0.06)   \\
minority    &               &       0.034   &       0.097*  \\
            &               &      (0.05)   &      (0.04)   \\
disting     &               &               &       0.439***\\
            &               &               &      (0.06)   \\
cons       &       0.529***&       0.530***&       0.518***\\
            &      (0.03)   &      (0.03)   &      (0.02)   \\
\hline  N           &     196   &     196   &     196   \\          
R$^{2}$           &       0.001   &       0.003   &       0.235   \\
\hline
\end{tabular}
\end{table}

I would like to add the statistical significance stars bellow, but I can't seem to add code with three multicolumn. I tried adding the following at the end of the table but does not seem to work:

\bottomrule
\vspace{-3mm}\\
\multicolumn{3}{l}{\textsuperscript{***}$p<0.01$, 
  \textsuperscript{**}$p<0.05$, 
  \textsuperscript{*}$p<0.1$,

How could I add the textsuperscripts?

You can, in fact, use a \multicolumn and \addlinespace from the booktabs package:

\documentclass{article}
\usepackage{booktabs}

\begin{document}

\begin{table}[htbp]\centering
\caption{Dependent Variable: Enrollment}
\begin{tabular}{c c c c}
\toprule
\textbf{Variable} & \textbf{Model 1} & \textbf{Model 2} & \textbf{Model 3}\\ 
\midrule
frl         &      -0.012   &      -0.052   &      -0.156** \\
            &      (0.04)   &      (0.06)   &      (0.06)   \\
minority    &               &       0.034   &       0.097*  \\
            &               &      (0.05)   &      (0.04)   \\
disting     &               &               &       0.439***\\
            &               &               &      (0.06)   \\
cons       &       0.529***&       0.530***&       0.518***\\
            &      (0.03)   &      (0.03)   &      (0.02)   \\
\midrule
 N           &     196   &     196   &     196   \\          
R$^{2}$           &       0.001   &       0.003   &       0.235   \\
\bottomrule
\addlinespace[1ex]
\multicolumn{3}{l}{\textsuperscript{***}$p<0.01$, 
  \textsuperscript{**}$p<0.05$, 
  \textsuperscript{*}$p<0.1$}
\end{tabular}
\end{table}

\end{document}

Below there's another possibility using the ctable package; I used some boxes to heide the width of the superscripted characters:

\documentclass{article}
\usepackage{ctable}
\usepackage{booktabs}

\begin{document}

\ctable[
  notespar,
  caption={Dependent Variable: Enrollment}
]{c c c c}
{\tnote[*]{$p<0.1$}\tnote[**]{$p<0.5$}\tnote[***]{$p<0.01$}}{
\toprule
\textbf{Variable} & \textbf{Model 1} & \textbf{Model 2} & \textbf{Model 3}\\ 
\midrule
frl         &      -0.012   &      -0.052   &      -0.156\tmark[{\makebox[0pt][l]{**}}] \\
            &      (0.04)   &      (0.06)   &      (0.06)   \\
minority    &               &       0.034   &       0.097\tmark[{\makebox[0pt][l]{*}}]  \\
            &               &      (0.05)   &      (0.04)   \\
disting     &               &               &       0.439\tmark[{\makebox[0pt][l]{***}}]\\
            &               &               &      (0.06)   \\
cons       &       0.529\tmark[{\makebox[0pt][l]{***}}]&       0.530\tmark[{\makebox[0pt][l]{***}}]&       0.518\tmark[{\makebox[0pt][l]{***}}]\\
            &      (0.03)   &      (0.03)   &      (0.02)   \\
\midrule  
N           &     196   &     196   &     196   \\          
R$^{2}$           &       0.001   &       0.003   &       0.235   \\
\bottomrule}

\end{document}

Without booktabs nor ctable, you can do something like:

\documentclass{article}
\usepackage{booktabs}

\begin{document}

\begin{table}[htbp]\centering
\caption{Dependent Variable: Enrollment}
\begin{tabular}{c c c c}
\hline\hline
\textbf{Variable} & \textbf{Model 1} & \textbf{Model 2} & \textbf{Model 3}\\ 
\hline
frl         &      -0.012   &      -0.052   &      -0.156** \\
            &      (0.04)   &      (0.06)   &      (0.06)   \\
minority    &               &       0.034   &       0.097*  \\
            &               &      (0.05)   &      (0.04)   \\
disting     &               &               &       0.439***\\
            &               &               &      (0.06)   \\
cons       &       0.529***&       0.530***&       0.518***\\
            &      (0.03)   &      (0.03)   &      (0.02)   \\
\hline
 N           &     196   &     196   &     196   \\          
R$^{2}$           &       0.001   &       0.003   &       0.235   \\
\hline
\\[-1.75ex]
\multicolumn{3}{l}{\textsuperscript{***}$p<0.01$, 
  \textsuperscript{**}$p<0.05$, 
  \textsuperscript{*}$p<0.1$}
\end{tabular}
\end{table}

\end{document}

You can use \multicolumn and \cmidrule from booktabs package.

\documentclass{article}
\usepackage{booktabs}
\begin{document}
  \begin{tabular}{c c  c c}
\toprule
&\multicolumn{2}{c}{Probability of} & Average \\\cmidrule{2-3}
Capital, $a$ & Ruin & Success &  duration, $N_a$  \\
\midrule
9 & 0.1 & 0.9 & 0.9 \\
9 & 0.1 & 0.9 & 0.9 \\ \bottomrule
\end{tabular}
\end{document}

enter image description here

For more details on \cmidrule refer to the documentation of booktabs package.

A possible refinement for the last header:

\documentclass{article}
\usepackage{booktabs}

\newcommand{\smashedcell}[1]{%
  \strut\smash{\begin{tabular}[b]{@{}c@{}}#1\end{tabular}}%
}

\begin{document}
  \begin{tabular}{c c  c c}
\toprule
&\multicolumn{2}{c}{Probability of} & \\
\cmidrule{2-3}
Capital, $a$ & Ruin & Success & \smashedcell{Average \\ duration, $N_a$}  \\
\midrule
9 & 0.1 & 0.9 & 0.9 \\
9 & 0.1 & 0.9 & 0.9 \\ 
\bottomrule
\end{tabular}
\end{document}

[Tex/LaTex] Formatting *** in a regression result table

You may want to use the dcolumn package for this purpose: It provides a column type called D which serves to align numbers in a column on the decimal marker without need for further intervention to handle symbols such as (, ), and *.

Because the contents of a D column are automatically typeset in math mode, there's also no need to specify opening and closing $ markers. However, if you have a cell -- say, in the header row -- in a D-type column that contains some text or other mostly non-numeric material, be sure to encase it in a \mulicolumn{1}{c}{<some text>} macro.

In the MWE below, I've modified the numbers relative to your code to make them conform to the structure of the numbers in the screenshot you posted.

enter image description here

\documentclass{article}
\usepackage{dcolumn}
\newcolumntype{d}[1]{D..{#1}} % for alignment of numbers on decimal marker
\begin{document}
\begin{tabular}{@{} r d{4.6} @{}} 
\hline  % just to mark width of tabular env.
A & 0.123^{***}\\   & (-12.11)\\    
B & 0.456^{*}  \\   &  (-8.45)\\
C & 0.789^{**} \\   &  (12.34)\\     
\end{tabular}
\end{document}
