The Collaborative Coefficient (Ajiferuke *et al.* 1988) is another measure of the degree of collaboration within a set of publications. It is calculated as:

where *f _{a}* is the number of publications having

# of Authors (a) | 1 | 2 | 3 | 4 |
---|---|---|---|---|

# of Publications (f)_{a} | 5 | 3 | 3 | 5 |

Quotient (f/_{a}a) | 5.00 | 1.50 | 1.00 | 1.25 |

The sum of the quotients is 8.75, which yields a collaborative index of 0.4531.
