I use the amcs:

\documentclass{amcs}
\begin{document}
\[ \frac {SySM_Accuracy - Ens_Accuracy}  \sqrt{ \frac {SySM_Accuracy * (1-SySM_Accuracy) } {number of testing rec } + \frac {Ens_Accuracy * (1-Ens_Accuracy) } {number of testing rec } } }\]
\end{document}

Following is the result that exceeds the paragraph column. How can I match it to the template?

following result

    please \mathrm{SySM}_{\mathrm{Accuracy}} ! Seeing Accuracy typeset as math italic is more painful on the eye than overprinting the next column... (especially if only the A is subscripted) Commented Oct 31, 2016 at 14:09
  • Thanks David. Can you please elaborate, I couldn't understand what to do.

  • Unrelated to the overprinting (except it will make the formula narrower) use \mathrm{SySM}_{\mathrm{Accuracy}} not SySM_Accuracy look at the image you have posted with the A being a subscript and ccuracy being set not subscripted and spaced out so that it looks like a product of variables, not a word) (similarly the denominator is unreadable and should be \text{number of testing rec} so that it uses a proper font and has word spaces Commented Oct 31, 2016 at 14:17
  • it is hard to suggest how to make the formula narrower without subject knowledge. In particular do you have to subscript your terms with Accuracy If you used something else eg Acc the expression would probably fit. Commented Oct 31, 2016 at 14:19
  • Thanks. Can you please help me to rephrase the formula? I changed it and I have errors.

You have no hope of fitting that beast in a narrow column. Use a symbol for the secondary fractions.

\documentclass{amcs}
\usepackage{amsmath}

\usepackage{lipsum} % just for the example

\newcommand{\tvar}[2]{%
  \mathrm{#1}_{\mathrm{#2}}%
}

\begin{document}

\title{Title}
\author[ad1][]{First name LAST NAME}

\correspondingauthor{Fifth AUTHOR}

\address[ad1]{Institute of xxx xxx xxx xxx\\ University of xxx xxx, 
  Address xxx xxx xx xxx xxx\\ e-mail: \url{xxx xx xxx}}

\maketitle

\lipsum*[1-3]
\[ 
\frac
  {\tvar{SySM}{Accuracy} - \tvar{Ens}{Accuracy}}
  {\sqrt{F(\tvar{SySM}{Accuracy})+F(\tvar{Ens}{Accuracy})}}
\]
where
\[
F(x)=\frac{x(1-x)}{\textup{number of testing rec}}
\]
\lipsum

\end{document}

By help of mathools package you can obtain:

enter image description here

\documentclass[twocolumn]{article}
\usepackage{mathtools}
\usepackage{lipsum}
\begin{document}
\[ 
\frac{\mathrm{SySM}_{\mathrm{Accuracy}} - \mathrm{Ens}_{\mathrm{Accuracy}}} 
{\sqrt{\splitdfrac{\frac{\mathrm{SySM}_{\mathrm{Accuracy}} * (1-\mathrm{SySM}_{\mathrm{Accuracy}})} 
         {\text{number of testing rec}} + }
                  {\frac{\mathrm{Ens}_{\mathrm{Accuracy}}* (1-\mathrm{Ens}_{\mathrm{Accuracy}})} 
    {\text{number of testing rec}} }
    }
}
\]
\lipsum
\end{document}

However, more nice result you will obtain if you will obey David Carlisle instructions in his comments above.
