mComb: Modified Dempster's Combination Operator In EvCombR: Evidence Combination in R

Description

Combine evidence in the form of mass functions using modified Dempster's combination operator.

Usage

 `1` ```mComb(x,y,z) ```

Arguments

 `x` single mass function or a list of mass functions `y` single mass function if `x` is a single mass function, a prior distribution or missing if `x` is a list `z` prior distribution if `x` and `y` are mass functions, otherwise missing

Details

The prior distribution is provided in the form of a list where the names are equivalent to the state space. See the examples.
