{title:Options for predict}

{phang}
{opt xb}, the default, calculates the fitted values{hline 2}the prediction of 
   xb for the specified equation.  This is the linear
   predictor from the fitted regression model; it does not apply the estimate
   of rho to prior residuals.

{phang}
{opt stdp} calculates the standard error of the prediction for the specified
   equation, in other words, the standard error of the predicted expected
   value or mean for the observation's covariate pattern.  This is also
   referred to as the standard error of the fitted value.

{pmore}
   As computed for {opt prais}, this is strictly the standard error from the
   variance in the estimates of the parameters of the linear model and assumes
   that rho is estimated without error.

{phang}
{opt residuals} calculates the residuals from the linear prediction.
