# Class "mixtureCopula"

### Description

The `mixtureCopula`

contains two copulas that are combined in a convex manner to a new copula.

### Objects from the Class

Objects can be created by calls of the form `new("mixtureCopula", ...)`

or by calling the constructor `mixtureCopula`

.

### Slots

`memberCops`

:Object of class

`"list"`

: holding the copulas used in the convex combination.`dimension`

:Object of class

`"integer"`

: the dimension of both input and the resulting copula.`parameters`

:Object of class

`"numeric"`

: the set of parameters for the first and second copula as well as the mixing coefficient.`param.names`

:Object of class

`"character"`

: names of all parameters.`param.lowbnd`

:Object of class

`"numeric"`

: lower bounds of all parameters.`param.upbnd`

:Object of class

`"numeric"`

: upper bounds of all parameters.`fullname`

:Object of class

`"character"`

: the name of the copula.

### Extends
