If the estimated ACVF (the estimated PACF) is essentially zero after some time lag, then the underlying time series can be conveniently modeled with an MA (AR) process---and no general ARMA sequence has to be fitted. (ACVF). This allows the door system to obtain different speeds and accelerations in the opening and closing directions. The Schindler IDD (Integrated Door Drive) unit controls the door motion, speed, acceleration, position and closing force limitation via a closed-loop system that includes an internal encoder for position and velocity reference.

Mean, Autocovariance, Stationarity A time series {Xt} has mean function µt = E[Xt] and autocovariance function γX(t+h,t) = Cov(Xt+h,Xt) = E[(Xt+h −µt+h)(Xt − µt)]. It is stationary if both are independent of t. Then we write γX(h) = γX(h,0). The autocorrelation function (ACF) is
