The `vcov`

method for `mlogit`

objects extract the
covariance matrix of the coefficients, the errors or the random
parameters.

`object` |
a |

`what` |
indicates which covariance matrix has to be extracted :
the default value is |

`type` |
with this argument, the covariance matrix may be returned (the default) ; the correlation matrix and the standard deviation vector may also be extracted. |

`reflevel` |
relevent for the extraction of the errors of a multinomial probit model ; in this case the covariance matrix is of error differences is returned and, with this argument, the alternative used for differentiation is indicated. |

`...` |
further arguments. |

This new interface replaces the `cor.mlogit`

and
`cov.mlogit`

functions which are deprecated.
