[R] level -- Set default confidence level
set level # [, permanently]
# is any number between 10.00 and 99.99 and may be specified with at most
two digits after the decimal point.
set 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.
permanently specifies that, in addition to making the change right now,
the level setting be remembered and become the default setting when
you invoke Stata.
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 level(#) option. When you do not
specify the option, the confidence intervals are calculated for the
default level set by set level or for 95% if you have not reset it.
Note concerning estimation commands
All estimation commands can redisplay results when they are typed without
arguments; see estcom. The width of the reported confidence intervals is
a property of the display, not the estimation. For example,
. sysuse auto
. regress mpg weight displ
. regress, level(90)
(output reappears, this time with 90% confidence intervals)
. set level 90
. set level 99, permanently
