Carcass composition, plasma protein, and hematocrit determinations were carried out on normal adult male chickens, and on adult males depleted by starvation for 4 weeks. For the first 2 weeks of depletion, N excretion was also determined for the starved animals. The following observations were reco...
The definition of the expectation of a random variable can be motivated both by the concept of a weighted average and through the use of the physics concept of the center of gravity, or the balancing point of a distribution of weights. We first examine the case of a discrete random variable...

In this paper, we derive an expectation formula of a random variable having distribution W(x;q). As applications of the expectation formula, we give a transformation formula and an expansion of Sears 23 transformation formula. 关键词: Andrews–Askey integral Probability distribution W(x,q Al-Sal...
Thus, we can think of g(y)=E[X|Y=y]g(y)=E[X|Y=y] as a function of the value of random variable YY. We then write g(Y)=E[X|Y].g(Y)=E[X|Y]. We use this notation to indicate that E[X|Y]E[X|Y] is a random variable whose value equals g(y)=E[X|Y=y]g(y...
In probability and statistics, the expectation or expected value, is the weighted average value of a random variable.
