Mathematics

The syntax for entering mathematics on the wiki is almost identical to that of standard AMSLaTeX.

• To enter inline math, surround statements by dollar signs:

Let $\varepsilon \gt 0$.  If for any $x$ there exists a $\delta \gt 0$ such that ...

Let $\epsilon >0$. If for any $x$ there exists a $\delta >0$ such that …

• To enter display mode (unnumbered) equations:

$$ \Pr(a \vert x, \theta) = \sum_{o \in \mathcal{O}} \Biggl\lbrace
    \int \chi \Bigl[ \alpha(u(x,\varepsilon,\theta),o) = a \Bigr]\,
       dG(\varepsilon) \Biggr\rbrace
    \mu(o \vert x, \theta) $$

• Numbered labeled displayed equations with references:

\[
  \label{reference}
  q_a(z) = \sigma_a^{-1} \exp\left[-\frac{\gamma + z}{\sigma_a}\right]
\]
Referring back to (eq:reference), or \eqref{reference}.

Referring back to (1), or (1).

• Note that the symbols < and > are not available, as in standard LaTeX. Use \lt and \gt instead.

See the itex commands page for a comprehensive list of supported math commands.

Categories

All Pages and Recently Revised can display all pages on the wiki, or only those pages that belong to a particular category. For example, here is a list of all pages in Help category

To add categories to a page, add a line like the following to the bottom of the page:

category: Statistics, Economics

It is customary to put the categories line at the bottom of the page (as you can see on this page). In order to make the categories invisible, use:

:category: InvisibleCategory

Miscellaneous

• Horizontal rules are produced by three or more asterisks or hyphens on a separate line:

A short rule

- - - -

A long rule
