This means that if you ran a probability experiment over and over, keeping track of the results, the expected value is the average of all the values obtained. But your right, for example average waiting time, would in my head, be also the expected time to … Then the expectedvalue of g(X) is given by E[g(X)] = X x g(x) p(x). operator The name of the function that is wrapped.

Found insideThe text includes many computer programs that illustrate the algorithms or the methods of computation for important problems. The book is a beautiful introduction to probability theory at the beginning level. Found inside – Page 91Another interpretation of the expected value of the random variable X is to view it as a weighted mean . Code to compute the expected value using ( 3 . 4 ) and using the function weighted . mean ( ) is A > x < - c ( 1 , 5 , 30 ) > px < - c ( 0 . 5 , 0 . Except I tend to use (IMHO ) average for simple average I.e expected value of X say, whilst expected value is usually a function. Interestingly, the acquisition function cannot be interpreted as computing a natural expected utility function. Follow edited Mar 16 '16 at 17:31. johnbowen. I know that the expected value of flipping the coin once is $\frac{1}{2}(2) - \frac{1}{2}(1) =0.50$ Would the expected value be 500? (16) Share.
