public class Coupling
extends AbstractRatioMetric

Coupling metric Efferent coupling (Ce): The number of types inside this assembly that depends on types outside this assembly. High efferent coupling indicates that the concerned assembly is dependant. Notice that types declared in framework assemblies are taken into account. see http://www.ndepend.com/Metrics.aspx#EfferentCoupling Here it is the ratio of the number of accesses between the two component candidates to the total number of accesses
