Define Expectation value. Expectation value synonyms, Expectation value pronunciation, Expectation value translation, English dictionary definition of Expectation value. n. 1. A quantity expressing a typical or average value of a random variable. 2. The
E(Y |X) is our best predictor of Y based on X. Best means it is the function of X with the lowest mean squared error (expected squared di↵erence between Y and prediction of Y ). It is called the Minimum Mean Square Estimate (MMSE) Theorem Let X, Y bejointly Normal random vari...
We consider a channel $Y=X+N$ where $X$ is a random variable satisfying $\\mathbb{E}[|X|]<\\infty$ and $N$ is an independent standard normal random variable. We show that the minimum mean-square error estimator of $X$ from $Y,$ which is ... W Alghamdi,FP Calmon 被引量: ...
We introduce the notion of a random mean generated by a random variable and give a construction of its expected value. We derive some sufficient conditions
conditional expectation(条件期望讲义)A Conditional expectation A.1Review of conditional densities,expectations We start with the continuous case.This is sections6.6and6.8in the book.Let X,Y be continuous random variables.We defined the conditional density of X given Y to be f X,Y(x,y)f ...
We study the (weak) equilibrium problem arising from the problem of optimally stopping a one-dimensional diffusion subject to an expectation constraint on
square Gaussian random variablecovariance functionIn this paper, we had constructed the goodness-of-fit tests incorporating several components, like expectation and covariance function, for identification of a non-centered stationary Gaussian stochastic process. For the construction of the corresponding ...
In particular, the representations of symmetric martingales are obtained using only the stochastic integrals. We obtain the martingale representation in Theorem 5.1 for almost all square-integrable martingales. This result essentially provides a complete answer to the question of representation for the ...
