These statistics are available both in and out of sample; type

{title:Options for predict}

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

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

{phang}
{opt u} produces estimates of minus the natural log of the technical
efficiency via E(u|e).

{phang}
{opt m} produces estimates of minus the natural log of the technical
efficiency via M(u|e).

{phang}
{opt te} produces estimates of the technical efficiency
via {bind:E{exp(-su)|e}}.

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

{pmore}
The first new variable will contain the derivative of the log likelihood with
respect to the regression equation.

{pmore}
The second new variable will contain the derivative of the log likelihood with
respect to the second equation ({hi:lnsig2v}).

{pmore}
The third new variable will contain the derivative of the log likelihood with
respect to the third equation ({hi:lnsig2u}).
