What is a stationary random process?
A random process is called stationary if its statistical properties do not change over time. For example, ideally, a lottery machine is stationary in that the properties of its random number generator are not a function of when the machine is activated.
What is an example of a stationary method?
White noise is the simplest example of a stationary process. An example of a discrete-time stationary process where the sample space is also discrete (so that the random variable may take one of N possible values) is a Bernoulli scheme.
How do you know if a random process is stationary?
Intuitively, a random process X(t),t∈J is stationary if its statistical properties do not change by time. For example, for a stationary process, X(t) and X(t+Δ) have the same probability distributions. In particular, we have FX(t)(x)=FX(t+Δ)(x), for all t,t+Δ∈J.
What is random process with example?
Tossing the die is an example of a random process; • The number on top is the value of the random variable. 2. Toss two dice and take the sum of the numbers that land up. Tossing the dice is the random process; • The sum is the value of the random variable.
