Realization
In probability and statistics, a realization or observation (also called observed value) of a random variable or random element is the value that is actually observed or measured.1
In probability theory, a random variable is a function
Xdefined from a sample space\Omegato the state space.
If an element in
\Omegais mapped to an element in state space byX, then that element in state space is a realization. That is, at a point\omega \in \Omega, the valuex = X(\omega)is called a realization ofX
