Credal Combination Operator (restricted to intervals)
Description
Combine evidence in the form of credal sets (based on intervals) using the credal combination operator (also known as the robust Bayesian combination operator). The resulting credal set is approximated by using probability intervals.
Usage
cComb(x,y)
Arguments
x |
credal set or a list of credal sets |
y |
credal set if |
Value
credal set

# construct a state space
stateSpace <- c("a", "b", "c")
# construct credal sets with the given state space
c1 <- credal(c(0.1, 0.1, 0.1), c(0.8, 0.8, 0.8), stateSpace)
c2 <- credal(c(0.2, 0.2, 0.2), c(0.9, 0.9, 0.9), stateSpace)
# combine the credal sets
