Before revision: We study the effects of rounding on the moments of a random variable . Specifically, given a random variable X and its rounded counterpart rd(X), we study | \mathbf{E - \mathbf{E | for non-negative integer k.
After revision: We study the effects of rounding on the moments of a random variable . Specifically, given a random variable X and its rounded counterpart rd(X), we study | \mathbb{E - \mathbf{E | for non-negative integer k.
