have zero covariance. The formula for the variance of a sum of two random variables can be generalized to sums of more than two random variables (seevariance of the sum of n random variables). Bilinearity of the covariance operator The covariance operator is linear in both of its arguments....
ex·pect·ed value (ĭk-spĕk′tĭd) n. 1.A quantity expressing a typical or average value of a random variable. 2.The sum (for discrete variables) or integral (for continuous variables) of the product of a random variable with its probability density function, over its range of val...
The performance of a discrete-time linear estimator which receives compressed, quantized measurements is studied. Upper and lower bounds for the expected value of the estimate error covariance, along with the necessary equations for computing the probability of processing a measurement under the proposed...

are said to be statistically consistent if their dispersion is not greater than what can be expected from the normal consistency model which postulates that the joint n-variate sampling pdf of x is normal N(1[micro], D) with unknown expected value 1[micro] and variance-covariance matrix D ...

The degree of uncertainty of a random vector is defined in terms of a covariance matrix. Some managerial interpretations are also given.关键词: Theoretical or Mathematical/ linear programming management science stochastic processes/ stochastic linear program degree of uncertainty parameters optimal value ...
The expected value of a discrete random variable X is calculated as follows:μ = Σx * P(x) Here,x are all the possible values that can be present in the variable X. P(x) is the probability of x.The expected value provides a measure of central tendency for a random variable....
True or False: The continuous uniform distribution describes a random variable, defined on the interval (a, b), that has an equally likely chance of assuming values within a specified range. True or False: If two random variables X and Y have a covariance of 0,...
