Description Usage Arguments Value Background References See Also Examples

Compute compute the mode of a univariate or multivariate SEC distribution.

1 | ```
modeSECdistr(dp, family, object=NULL)
``` |

`dp` |
a numeric vector (in the univariate case, for class |

`family` |
a character string which identifies the parametric
family among those admissible for classes |

`object` |
an object of class |

a numeric vector

The mode is obtained through numerical maximization. In the multivariate case, the problem is reduced to a one-dimensional search using Propositions 5.14 and 6.2 of the reference below.

and `extractSECdistr`

,

`SECdistrUv-class`

and `SECdistrMv-class`

for methods `mean`

and `vcov`

which compute the mean (vector)
and the variance (matrix) of the `object`

distribution
