{title:Special-interest postestimation commands}

{pstd}
{cmd: estat alternatives} displays summary statistics about the alternatives
in the estimation sample and provides a mapping between the index numbers that
label the covariance parameters of the model and their associated values and
labels for the alternative variable.

{pstd}
{cmd: estat covariance} computes the estimated variance-covariance matrix for
the alternatives.  The estimates are displayed, and the variance-covariance
matrix is stored in {hi:r(cov)}.

{pstd}
{cmd: estat correlation} computes the estimated correlation matrix for the
alternatives.  The estimates are displayed, and the correlation matrix is
stored in {hi:r(cor)}.

{phang}
{opt pr}, the default, calculates the probability that an alternative {it:j}
is chosen in case {it:i}.

{phang}
{opt xb} calculates the linear prediction for alternative {it:j} and case
{it:i}.

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