## Class "plackettCopula" of Plackett Copulas

### Description

The Plackett copula class.

### Objects from the Class

Objects can be created by `new("plackettCopula", ...)` but are typically produced by `plackettCopula(alpha)`.

### Slots

`dimension`:

  Numeric (scalar), the dimension of the copula.

`exprdist`:

  a length two `expression` with expressions for the CDF and PDF of the copula.

`parameters`:

  a number (numeric vector of length one) specifying the non negative parameter.

`param.names`:

  the `"character"` string `"alpha"`.

`param.lowbnd`:

  the number `0`.

`param.upbnd`:

  the number `Inf`.

`fullname`:

  (deprecated; do not use!)

### Methods

Typical copula methods work, see `"plackettCopula"` and use `methods(class = "plackettCopula")`.

### Extends

Class `"plackettCopula"` extends class `"copula"` directly.
