{title:Options for predict}

{dlgtab:Main}

{phang}
{opt pr}, the default, calculates the probability of a positive outcome.

{phang}
{opt xb} calculates the linear prediction.

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

{phang}
{opt scores} calculates equation-level score variables.

{pmore}
The first new variable will contain {bind:d(ln L_j)/d(x_j b)}.

{pmore}
The second new variable will contain {bind:d(ln L_j)/d(ln(alpha))}.

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