nuisance parameters meaning in English
【统计学】多余参量。
Examples
- Empirical likelihood ratio confidence regions with a nuisance parameter for dependent samples
相依样本下带有讨厌参数的经验似然比置信区域 - The least square estimation in linear model is used to derive the two - stage estimation of the item parameter vector 1 of j th item as follows : noting that xj consists of the nuisance parameters s , j , j , were updated so that the estimation of 6 s could be renewed
修正进而修正x _ j和，从而形成一种新的估计方法?双重两步迭代估计蒙特卡洛模拟结果显示，双重两步迭代估计提高了估计对真值的恢复能力。 - Abstract : since the multiple failures situation is not uncommon in the clinical medicine , we explore the use of proportional odds model to the multivariate interval - censored data . the approach is based on the conditional logistic regression , which prevents the complications in the existence of nuisance parameters . the estimation of parameters is obtained by the newton - raphson algorithm . the sandwith estimator for the covariance is made according to the situation where there is correlation in the score statistic . simulations are also presented to assess the accuracy of the procedure
