Smoothing property of conditional expectation
Webinfinitesimal generator, we construct a family (semigroup) of conditional expectation operators.The operators exploit the time-invariant Markov structure. Each operator in this family is indexed by the forecast horizon, the interval of time between the infor-mation set used for prediction and the object that is being predicted. Operator methods WebDefinition 1. The conditional expectation of Ygiven X= x, denoted by E[Y jX= x] and occasionally by E[Y jx], is the expectation of the distribution represented by p(yjx). That is, …

The optimal bandwidths are obtained with respect to weak and almost sure convergences.

Webter in taking expectations, so E[E[X jG]Z] = E[YZ] = E[XZ] for all bounded G-measurable Z, and therefore Y has the defining properties of a conditional expecta-tion of X given G.
