[Tex/LaTex] How to write something above and below the signs

math-modemath-operators

I have a relation called Likelihood Ratio Test which has a special format. As you see in the picture, there are two non-equality signs and also somethings above and below them. How can I write these symbols?

You can use a \Vectorstack, where the baselineskip of the stack may be set to the desired value. As Bernard points out, a \Vectorstack is actually a \Centerstack that is automatically processed in math mode.

\documentclass{article}
\usepackage{stackengine}
\begin{document}
\[
  \setstackgap{L}{.7\baselineskip}
  \Lambda(y) = \frac{p(y{\mid}H_1)}{p(y{\mid}H_0)}
  \Vectorstack{H_1 > < H_0}
  \lambda.
\]
\end{document}

You can use \mathmakebox or \mathclap (thanks to Andrew) from mathtools

\documentclass{article}
\usepackage{mathtools}

\begin{document}
\begin{equation*}
\begin{split}
S_n &=                 2^iS_{n-i}+2^i-1\\
    &\stackrel{\mathmakebox[\widthof{=}]{\mathrm{IH}}}{=}  2^i(2^1S_{n-i-1}+2^1-1)+2^i-1\\
    &=                 2^{i+1}S_{n-i-1}+2^{i+1}-1
\end{split}
\end{equation*}
\end{document}

You can use align* also instead of equation* and split

\documentclass{article}
\usepackage{mathtools}

\begin{document}
\begin{align*}
S_n &=                 2^iS_{n-i}+2^i-1\\
    &\stackrel{\mathclap{\mathrm{IH}}}{=}  2^i(2^1S_{n-i-1}+2^1-1)+2^i-1\\
    &=                 2^{i+1}S_{n-i-1}+2^{i+1}-1
\end{align*}
\end{document}

Please note that I have changed IH to \mathrm{IH}. (Thanks to egreg).
