Yager's Combination Operator
Combine evidence in the form of mass functions using Yager's combination operator.
yComb(x,y)
x |
single mass function or a list of mass functions |
y |
single mass function if |
mass function (massQ-class)
Yager's combination operator is quasi-associative and therefore we need to keep track of the mass on the empty set by using the class massQ.
