The '''`estimates`''' command is an interface to estimation results.

<<TableOfContents>>

----



== Usage ==

There are several subcommands to the `estimates` command.



=== Store ===

After fitting a model, try:

{{{
estimates store somename
}}}

The estimates can be accessed like:

{{{
estimates table somename
}}}

If a name is omitted from any `estimates` command, then the 'active' or 'latest' estimate results are used. Most commands allow multiple stored estimate results.



=== Stats ===

Try:

Options exist to:

 * `aiccorrected`: report AICc instead of AIC
 * `aicconsistent`: report CAIC instead of AIC
 * `all`: report all criteria



=== Table ===

Try:

{{{

      weight | -.00656711

}}}

Note that the output of `estimates table` depends strongly upon the estimate results being used.

Note furthermore these options:

 * `stats(statslist)` displays the specified statistics with the table
 * `keep(varlist)` shows only the specified coefficients
 * `drop(varlist)` suppresses display of the specified coefficients
 * `b` displays coefficients
   * `b(%format)` implies `c` and sets the print format 
 * `se` displays standard errors
   * `se(%format)` implies `se` and sets the print format 
 * `t` displays [[Statistics/TestStatistics|test statistics]]
   * `t(%format)` implies `t` and sets the print format 
 * `p` displays [[Statistics/TestStatistics|p values]]
   * `p(%format)` implies `p` and sets the print format 
 * `varwidth(#)` sets the display width of variable names
 * `varlabel` displays variable labels rather than variable names
 * `modelwidth(#)` sets the display width of model names

Finally, `estimates table` stores the following results:

 * `r(coef)`: matrix of coefficients
 * `r(stats)`: matrix of statistics, if the `stats(statlist)` option was used
