{title:Options for predict}

{dlgtab:Main}

{phang}
{opt xb}, the default, calculates the linear prediction using the mean
parameter vector.

{phang}
{opt stdp} calculates the standard error of the linear prediction.

{phang}
{opt group(group)} calculates the linear prediction using the best linear
predictors for group {it:group}.

{phang}
{opt nooffset} is relevant only if you specified {opth offset(varname)} for
{cmd:xtrc}.  It modifies the calculations made by {cmd:predict} so that
they ignore the offset variable; the linear prediction is treated as xb rather
than xb + offset.
