## Gibbs update for dyadic variance

### Description

Gibbs update for dyadic variance

### Usage

```
rs2_fc(Z, rho,offset=0,nu0=NULL,s20=NULL)
```

### Arguments

`Z` |
n X n normal relational matrix |

`rho` |
current value of rho |

`offset` |
matrix of the same dimension as Z. It is assumed that Z-offset
is equal to dyadic noise, so the offset should contain any additive and
multiplicative effects (such as |

`nu0` |
prior degrees of freedom |

`s20` |
prior estimate of s2 |

### Value

a new value of s2
