components, then µ X 2 = lim →∞ R(τ) In mathematics and statistics, a stationary process (or a strict/strictly stationary process or strong/strongly stationary process) is a stochastic process whose unconditional joint probability distribution does not change when shifted in time. Consequently, parameters such as mean and variance also do not change over time. • A random process X(t) is said to be wide-sense stationary (WSS) if its mean and autocorrelation functions are time invariant, i.e., E(X(t)) = µ, independent of t RX(t1,t2) is a function only of the time diﬀerence t2 −t1 E[X(t)2] < ∞ (technical condition) • Since RX(t1,t2) = RX(t2,t1), for any wide sense stationary process X(t), MCQ Problems / Explanations. All last condition thus encompasses the first three and is only required for a process to be classifiable as a strictly stationary C ) The roots of the characteristic equation must all lie outside the unit circle Explanation : A stationary autoregressive process will have all the roots of its characteristic equation lying outside the unit circle - this is equivalent to saying that the roots must all be larger than one in absolute value. Stationary Waves Paper – 4 Selection of good quality MCQs (Multiple choice questions) for test preparation is an important task.

None of the above View Answer / Hide Answer The definition of stationary process “a stochastic process whose unconditional joint probability distribution does not change when shifted in time. Here is one technique of nonlinear time series model fitting, which makes use of the prior knowledge that the interaction between the terms are ‘simple’. Intuitively, a random process {X(t), t ∈ J } is stationary if its statistical properties do not change by time.

(a) If a process is not invertible, residuals can not be calculated for diagnostics purposes. Explanation: A random process is said to be Stationary in Strict Sense (SSS) if the joint probability distribution factor remains invariant to the translation of time origin. On the contrary, it is said to be Stationary in Wide Sense if mean value m x (t) is independent of time and the autocorrelation function Rx (t k, t i) depends only on the time difference (t k - t i ). Explanation: In Column chromatography, the stationary phase is made of solid and the mobile phase is made of liquid. It is carried out in a long glass column which has a stop-cock near the bottom.

on yarn and fell in love with the beading process pretty early on, but I'm talking about really falling in love with the beads themselves.
