摘要
In this paper, we start research into using intervals to bound the impact of bounded measurement errors on the computation of bounds on finite population parameters (descriptive statistics). Specifically, we provide a feasible (quadratic time) algorithm for computing the lower bound σ 2 on the finite population variance function of interval data. We prove that the problem of computing the upper bound σ2 is, in general, NP-hard. We provide a feasible algorithm that computes σ 2 under reasonable easily verifiable conditions, and provide preliminary results on computing other functions of finite populations. © Springer 2005.
