{title:Options for predict}

{phang}{opt xb}, the default, calculates the prediction of xb, the
fitted values, using the average effect of the absorbed variable.  Also see
{opt xbd} below.

{phang}{opt stdp} calculates the standard error of xb.

{phang}{opt dresiduals} calculates y - xb, which are the
residuals plus the effect of the absorbed variable.

{phang}{opt xbd} calculates xb + d_absorbvar, which are
the fitted values including the individual effects of the absorbed variable.

{phang}{opt d} calculates d_absorbvar, the individual
coefficients for the absorbed variable.

{phang}{opt residuals} calculates the residuals, that is, 
{bind:y - (xb + d_absorbvar)}.  

{phang}{opt score} is a synonym for {opt residuals}.
