Quick reference for estimation commands

__Description__

This entry provides a quick reference for Stata's estimation commands.
Because enhancements to Stata are continually being made, type **search**
**estimation commands** for possible additions to this list; see **[R] search**.

For a discussion of properties shared by all estimation commands, see
estcom.

For a list of prefix commands that can be used with many of these
estimation commands, see **[U] 11.1.10 Prefix commands**.
