where {it:k} is the number of outcomes in the model.

{synopt :{opt p:r}}predicted probability of a positive outcome; the default{p_end}

{synopt :{opt stdp}}standard error of linear prediction{p_end}
{synoptline}
{p2colreset}{...}
{p 4 6 2}
Note that you specify one new variable with {opt xb} and {opt stdp} and
specify either one or {it:k} new variables with {opt pr}.

{title:Options for predict}

{dlgtab:Main}

{phang}
{opt pr}, the default, calculates the probability of each of the
alternatives in the model or the probability of the outcome
specified in {opt outcome()}. If you specify {opt outcome()}, you only 
need to specify one new variable; otherwise, you must specify {it:k} new 
variables, one for each alternative in the model.

{phang}
{cmd:xb} calculates the linear prediction.
You must also specify the {opt outcome(outcome)}.

{phang}
{cmd:stdp} calculates the standard error of the linear prediction.
You must also specify the {opt outcome(outcome)}.

{phang}
{opt outcome(outcome)} specifies the outcome for which the statistic is to be
calculated. {opt equation()} is a synonym for {opt outcome()}: it does not
matter which you use, and the standard rules for specifying an
{opt equation()} apply.

{phang}
{opt scores} calculates equation-level score variables.  The number of score
variables created will be one less than the number of outcomes in the model.

{pmore}
Each new variable will contain the derivative of the log likelihood with
respect to a corresponding equation.
