Calculate the Expected Value of a Fuzzy Number
The calculation of the so-called expected value is one of possible methods to deffuzify a fuzzy number.
## S4 method for signature 'FuzzyNumber' expectedValue(object, ...)
object |
a fuzzy number |
... |
additional arguments passed to |
The expected value of A is defined as
EV(A) := (EI_U(A) + EI_L(A))/2,
where EI is the expectedInterval.
Returns a single numeric value.
