基于β分布的区间估计量化方法

Quantitative Methods of interval Estimation Based on the Distribution of β

区间估计是专家评价中的重要方法.针对区间估计的特点,构建了区间序列分布,分析了区间序列分布的特性和数字特征;结合β分布及其特性,提出了一种基于β分布的区间估计量化方法,着重探讨了用β分布拟合区间序列分布的原理方法;通过案例分析,表明该方法效果较好,并具有较好的普适性.

Interval estimation is an important method of expert evaluation. For the char- acteristics of interval estimation, constructed interval sequence distribution, analysis of the characteristics of the distribution of interval sequences and digital features; Combination of distribution and characteristics of β,β distribution was proposed based on quantitative methods of interval estimation, focused on the β distribution fit with the principle method of distribution of interval sequences;The case study shows that the method is better, and has good universality.
