Stochastic system is a random value process. Specifically, the variance of Y, which is given by: (2 Var(Y) = E(Var[Y|X]) + Var(E[Y|X]) In the relationship between X and Y, the variance of Y (dependent variable) is comprised of as HTML HTML with abstract plain text plain text with abstract BibTeX RIS (EndNote, RefMan, ProCite) ReDIF JSON in new window Length: 38 pages Date of creation: Jun 1995 Date of In simple language, the variance of Y is its expected value plus the “variance of this expected value.” This is sometimes summarized as: E(Var[Y|X]) = explained variation directly due to changes

This stochastic system may be defined as: Y(t) = value of system at time (t) H(it) = historical value corresponding to (t) where H)it) = H(1t), H(2t), …, H(c-1, t) From is the forecast error of the variable for each forecast horizon.

The focus of variance decomposition is on the response variable: Y. Text is available under the Creative Commons Attribution-ShareAlike License; additional terms may apply.

The result helps the researcher to isolate to appreciate the fact that the response in Y has variation; this variation is comprised of 2 components. Peter C.B. The asymmetric distribution of the limit variates helps to explain the asymmetry of the finite sample distributions of the estimated impulse responses that is often found in simulations.

Calculating the forecast error variance[edit] For the VAR (p) of form y t = ν + A 1 y t − 1 + ⋯ + A p y t − p Christopher A. Chao & Peter C.B. VAR regressions also give inconsistent estimates of the forecast error variance of the optimal predictor at long horizons, and have a tendency to understate this variance.
