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

`MC` |
A |

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

`Correction` |
A string containing one of the possible corrections accepted by the bias-corrected entropy function (see details) or |

`Tree` |
An object of class |

`Normalize` |
If |

`Z` |
A relatedness matrix, |

`CheckArguments` |
Logical; if |

If `Tree`

is not `NULL`

, then phylogenetic entropy is calculated by `bcPhyloBetaEntropy`

; else, if `Z`

is not `NULL`

, then similarity-based entropy is calculated by `bcHqzBeta`

; else, neutral entropy is calculated by `bcTsallisBeta`

.

The reduced-bias beta entropy of each community is calculated and summed according to community weights.

Note that beta entropy is related to alpha entropy (if *q* is not 1) and cannot be compared accross communities (Jost, 2007). Do rather calculate the `BetaDiversity`

of the metacommunity.

An `MCentropy`

object containing entropy values of each community and of the metacommunity.
