plautrans {dst} | R Documentation |
Given a mass function defined on some subsets of a frame \Theta
, the application of the plausibility transformation to the singletons of \Theta
yields the probability distribution associated with this mass function.
plautrans(x)
x |
A bca mass function. |
We compute the plausibility measure of all the singletons of the frame of discernment. The probability distribution of the singletons is obtained from their plausibility measures.
The matrix of singletons with their plausibility transformation added in the last column.
