be integrated of order one, or I(1) – A stationary series without a trend is said to be. integrated of order 0, or I(0) Is AR model stationary? Contrary to the moving-average (MA) model, the autoregressive model is not always stationary as it may contain a unit root. Is ...
Indicate whether the following are true or false: a. The random telegraph signal process is a Gaussian random process. b. The Wiener process is a Gaussian random process. All stationary processes ar Given P(A and B) = 0.42, P(A) = 0.92, and P(B) = 0.05, are events A an...

3D laser scanners come in an impressive variety, tailored to various applications. They range from standalone devices – handheld or stationary and tripod-mounted – to complex industry-grade solutions, such as mobile or airborne laser scanning systems or robotic arms. Laser scanners use three types...
disk model, as shown in Fig.1. We determine the order of the images by the number of intersections between the light rays reaching the observer and the accretion disk: a single intersection represents the primary image, two intersections denote the secondary image, and three or more ...

Thedrifteris an R package that identifies concept drift in model structure or in data structure. Machine learning models are often fitted and validated on historical data under an assumption that data are stationary. The most popular techniques for validation (k-fold cross-validation, repeated cross...
Stationary distribution for the AR(1) model: In the special case of an AR(1)AR(1) process with auto-regression parameter |ϕ|<1|ϕ|<1, the auto-covariance function for the process is: γ(k)≡C(Xt,Xt+k)=ϕk1−ϕ2⋅σ2.γ(k)≡C(Xt,Xt+k)...
