xbeta is an open venue for organizing knowledge pertaining to econometrics, mathematics, statistics, and scientific computing. xbeta is a wiki and so pages are easy to create and edit using a combination of Markdown, a simple plain text markup language, and itex, a dialect of LaTeX. See the HowTo to get started.
Some useful entry points on the wiki are Recently Revised and All Pages. To learn how to edit pages, see the formatting rules for details about the wiki syntax or head to the Sandbox to practice editing pages by example. To keep the wiki clean and organized, there are a few style guidelines. See About and News for more information.
