{title:Description}

{pstd}
{cmd:set} {cmd:level} specifies the default confidence level for confidence
intervals for all commands that report confidence intervals.  The initial
value is 95, meaning 95% confidence intervals.  {it:#} may be between 10.00
and 99.99, and {it:#} can have at most two digits after the decimal point.


{marker option}{...}
{title:Option}

{phang}
{opt permanently} specifies that, in addition to making the change right now,
the {cmd:level} setting be remembered and become the default setting when you
invoke Stata.


{marker remarks}{...}
{title:Remarks}

{pstd}
To change the level of confidence intervals reported by a particular command,
you need not reset the default confidence level.  All commands that report
confidence intervals have a {opt level(#)} option.  When you do not
specify the option, the confidence intervals are calculated for the default
level set by {cmd:set} {cmd:level} or for 95% if you have not reset it.


{marker note}{...}
{title:Note concerning estimation commands}

{pstd}
All estimation commands can redisplay results when they are typed
without arguments; see {help estcom}.  The width of the reported confidence
intervals is a property of the display, not the estimation.  For example,

{phang2}{cmd:. sysuse auto}{p_end}
{phang2}{cmd:. regress mpg weight displ}{break}
        (output appears)

{phang2}{cmd:. regress, level(90)}{break}
       (output reappears, this time with 90% confidence intervals)
