Calculate E(Xy) at Karen Lockhart blog

Calculate E(Xy). we have $e [xy]=\int_ {\mathbb r\times\mathbb r}xyf (x,y)dx dy$ in general, where $f (\cdot,\cdot)$ is the cdf of $. We are interested in e(xy) because it is used for calculating the covariance. you take all possible pairs $(x,y)$, and for each pair, you multiply their product $xy$ by the probability. essentially, if an experiment (like a game of chance) were repeated, the expected value tells us the average result we’d see in the long run. Let’s use these definitions and. If g(x) ≥ h(x) for all x ∈ r, then e[g(x)] ≥ e[h(x)]. for example, if x is height and y is weight, e(xy) is the average of (height × weight). Another common property of random variables we are interested in is. theorem 1 (expectation) let x and y be random variables with finite expectations. e[x] = e[y] = 0 to measure the spread of a random variable x, that is how likely it is to have value of xvery far away from the. if x and y are 2 dependent variables, how does their combined expectation look?
