Function to obtain matrix of dyadic dominance indices corrected for chance from the observed sociomatrix.

1 |

`X` |
Empirical sociomatrix containing wins-losses frequencies in dyadic encounters. |

`names` |
Character vector with the names of individuals. This vector is NULL by default |

`getDij`

is only applied for square matrices in which the set of *n* actors is also the set of *n* partners. The matrices must also be numeric.

`Dij` |
Matrix of observed dyadic dominance indices corrected for chance. |
