用Bootstrap方法比较不同研究领域的h指数

Comparison of the h-index for Different Fields of Research Using Bootstrap Methodology

C. Malesios, S. Psarakis

摘要:

h指数的一个重要缺点是,它通常不能考虑研究人员的具体研究领域。通常,报告各个字段的平均和中值h指数值的样本点估计值是高度可变的,并且取决于特定样本,并且提供预测准确性的置信区间是有用的。在本文中,我们应用非参数bootstrap技术构建置信区间的h指数为不同的研究领域。通过这种方式,不需要对经验hindex的分布进行具体假设,也不需要大样本,因为该方法是基于对初始样本的重新采样。分析结果表明,各领域之间存在重大差异。大多数领域的平均值和中位数h指数的自举区间的性能似乎是相当令人满意的,所进行的模拟显示。

英文摘要:

An important disadvantage of the h-index is that typically it cannot take into account the specific field of research of a researcher. Usually sample point estimates of the average and median h-index values for the various fields are reported that are highly variable and dependent of the specific samples and it would be useful to provide confidence intervals of prediction accuracy. In this paper we apply the non-parametric bootstrap technique for constructing confidence intervals for the h-index for different fields of research. In this way no specific assumptions about the distribution of the empirical hindex are required as well as no large samples since that the methodology is based on resampling from the initial sample. The results of the analysis showed important differences between the various fields. The performance of the bootstrap intervals for the mean and median h-index for most fields seems to be rather satisfactory as revealed by the performed simulation.
