As a result, confidence intervals are constructed to predict the range of leak location. Experimental results demonstrate that the proposed method can localize the actual leak with an accurate coverage probability and satisfactorily match the ground-truth confidence intervals. In the considered scenario,...
Basic Confidence Limit Methods:包含4种参数型方法和3种非参数方法 基于分位数的Bootstrap CI 理论比较:对上述方法的精度进行比较,引申出ABC method以提升一定场景下的精度 CI反转假设检验 拓展:Double Bootstrap CI、多参数置信域、条件置信域 分享至
Compute the 95% confidence interval for the capability index by using 2000 bootstrap samples. By default, bootci uses the bias corrected and accelerated percentile method to construct the confidence interval. Get ci = bootci(2000,capable,y) ci = 2×1 0.5937 0.9900 Compute the studentized co...
即[2×θ^−w0.95∗,2×θ^−w0.05∗] ,被称为basic bootstrap confidence interval 。 ③除了上述两种方法,还有一种置信区间:bootstrap studentized confidence interval。 这种置信区间的构造思想是,根据中心极限定理,在相对多样本数量的情况下,总体均值近似服从正态分布,进而能得到t统计量 t=x¯−...
3.偏差矫正的Bootstrap百分位法(bias-corrected bootstrap interval):又叫偏差矫正和加速Bootstrap(accelerated bootstrap)。同样重复2的步骤,如果2构造的中位数恰好和原始样本的中位数相同,则选择Bootstrap百分位数法;若不相同,Edwards建议采用偏差矫正的Bootstrap百分位数法,其通过原始中位数在bootstrap样本中位数中的...
The bias-corrected and accelerated interval bootstrap method (BCa) [28] can be used to calculate confidence intervals with small sample sizes or extreme distributions. It is an extension of the percentile bootstrap method. In the percentile bootstrap method, the data are resampled with replacement...

The log likelihood profile method does not assume symmetry of the parameter uncertainty but it does use the likelihood ratio test (LRT) based on the change in NONMEM objective function value to predict the probability of the confidence interval. This ...
The results show that, for the same number of transfer function evaluations, the DKM method has equal or smaller error and confidence interval compared to ranking.doi:10.1007/s10596-009-9156-8Celine ScheldtDepartment of Energy Resources EngineeringJef Caers...
