# Reduced-bias beta diversity of a metacommunity

### Description

Calculates the reduced-bias beta diversity of order *q* between communities.

### Usage

1 2 |

### Arguments

`MC` |
A |

`q` |
A number: the order of diversity. Default is 1 for Shannon diversity. |

`Correction` |
A string containing one of the possible corrections accepted by |

`Tree` |
An object of class |

`Normalize` |
If |

`Z` |
A relatedness matrix, |

`CheckArguments` |
Logical; if |

### Details

Entropy is calculated by `BetaEntropy`

and transformed into diversity.

Diversity values of communities are not defined: community entropies are averaged to obtain the metacommunity entropy wich is transformed into diversity (Marcon et al., 2014).

### Value

An `MCdiversity`

object containing diversity value of the metacommunity.
