calc_swness_zscore | R Documentation |

The function calculates small-world-ness z-scores and 99\ using as null model the list of networks in the nullDist parameter.

```
calc_swness_zscore(g, nullDist, sLevel = 0.01, ncores = 0, weights = NA)
```

`g` |
igraph object |

`nullDist` |
list of igraph object with the null model simulations |

`sLevel` |
significance level to calculate CI (two tails) |

`ncores` |
number of cores to use paralell computation, if 0 sequential processing is used. |

a list with two data frames: one with indices z-scores and CI

`Clustering` |
Clustering coefficient, measures the average fraction of pairs of neighbors of a node that are also neighbors of each other |

`PathLength` |
Mean of the shortest paths between all pair of vertices |

`Modularity` |
modularity measures how separated are different groups from each other, the algorithm |

`zCC` , `zCP` , `zMO` |
Z-scores of Clustering,PathLength and Modularity with respect to a random Erdos-Renyi null model |

`CClow` , `CChigh` , `CPlow` , `CPhigh` , `MOlow` , `MOhigh` |
sLevel confidence intervals |

`SWness` , `SWnessCI` |
Small-world-ness and it CI value |

`isSW` , `isSWness` |
Logical variable signalling if the network is Small-world by the method of Marina 2018 or the method of Humprhies & Gurney 2008 |

Another data.frame with the values calculated for the nullDist.
