In statistical analysis, we usually use the observed sample values x1, . . . , xn to compute the values of several statistics v(x1;:::;xn) { such as sample mean, sample variance, etc. The usual formulas for these statistics implicitly assume that we know the exact values x1;:::;xn. In practice, the sample values e
