This chapter focuses on the expectation of random variables, particularly the expectation of elementary random variables. It presents proofs of the Lebesgue's theorem on monotone sequences and the Lebesgue's theorem on term by term integration. The chapter discusses signed measures and the Radon–Nik...
We consider the classical problem of nonparametric estimation of the mathematical expectation of a function of independent random variables. In contrast to the traditional formulation, it is assumed that some random variables have identical distributions. For estimation, there are the samples whose number...

I have an empirical distribution Sn(x)Sn(x) (= proportion of samples less than equal to x) from a random sample X1,X2,...,XnX1,X2,...,Xn for a random variable X∼FXX∼FX. Consider the random variable Tn(x):=n.Sn(x)Tn(x):=n.Sn(x). This is a binomial random variable...
In the second phase, edges which failed in phase one are removed, and a probabilistic kidney exchange problem is resolved by means of random variables which indicate if an edge not previously checked can be used or not. The objective is to maximize the expected size of the phase-two ...

Parameter estimation in this setting is known as the complete data case in that the values of all relevant random variables in our model (that is, the result of each coin flip and the type of coin used for each flip) are known. Here, a simple way to estimate θA and θB is to ...
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
XX Minimum Mean Squared Error (MMSE) Estimation Theminimum mean squared error (MMSE)estimate of the random variableXX, given that we have observedY=yY=y, is given by x^M=E[X|Y=y].x^M=E[X|Y=y]. Example XX XX Y=yY=y Solution ...
