Modified Dempster's Combination Operator
Combine evidence in the form of mass functions using modified Dempster's combination operator.
mComb(x,y,z)
x |
single mass function or a list of mass functions |
y |
single mass function if |
z |
prior distribution if |
The prior distribution is provided in the form of a list where the names are equivalent to the state space. See the examples.
