The coincidence factor is the reciprocal of the diversity factor. The simultaneity factor may be identical to either the coincidence factor or the diversity factor, depending on the sources of definition; the International Electrotechnical Commission defines the coincidence and simultaneity factors identically, with the diversity factor being their reciprocal.
