Calculation method
Calculation method
Potential permitted person-to-person links
Add permitted within-group and cross-group counts.
Within-group links
If included, use n(n−1)/2 per group for undirected links or n(n−1) for directed links.
Cross-group links
Each declared cross pair contributes size(from)×size(to); reverse pairs are distinct only in directed mode.
Total people in disjoint groups
Sum entered disjoint group member counts.
Symbols and units
- a
- Disjoint groups: name, member count
- b
- Permitted cross-group pairs: from group, to group; or none
- c
- Include within-group connections: yes or no
- d
- Connections: undirected or directed
Use the units shown. A list keeps the order in which you enter its values. The symbol ^ means “raised to the power of”.
Assumptions & limits
Assumptions & limits
- Counts potential links under disjoint membership and explicit permitted group pairs. It does not estimate real message traffic or assume every person should communicate with every other person.
