tstat specifies that t-statistics rather than standard errors are reported. The decimal places
displayed are set by auto
pvalue specifies that p-values (of t-statistics) rather than standard errors are reported. The
decimal places displayed are set by tdec.
ci specifies that confidence intervals of coefficients rather than standard error are reported.
The decimal places displayed are those set by bdec.
level(integer) specifies the confidence level, in percent, for confidence intervals. The default
is level(95) or as set by set level, see [U] Specifying the width of confidence intervals.
level does not affect the confidence levels of asterisks.
beta asks that normalized beta coefficients be reported rather than standard errors (see the beta
option of regress). The decimal places displayed are those set by bdec.
nocons specifies that the intercept (constant) coefficient estimate not be reported. This is not
needed when the preceeding estimation has no intercept coefficient.
noni specifies that the number of groups in a panel data regression not be reported (e.g. the
number of groups specified by the i( ) variable in xtreg). This option has an effect only
after xt regression commands.
