WebWhite Noise White noise processes are the fundamental building blocks of all stationary time series. We denote it t ∼WN(0,σ2) - a zero mean, constant variance and serially uncorrelated (ρ(t,τ) = 0, for τ>0 and any t) random variable process. Sometimes we demand a stronger property of independence.
