{title:Options for predict}

{dlgtab:Main}

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

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

{phang}
{opt u} produces estimates of the technical inefficiency via E(u[i,t]|e[i,t]).

{phang}
{opt m} produces estimates of the technical inefficiency via the mode,
M(u[i,t]|e[i,t]).

{phang}
{opt te} produces estimates of the technical efficiency, or the cost
efficiency when the {opt cost} option is specified.
