英文文献：Data revisions and the statistical relation of global mean sea-level and temperature-数据修正和全球平均海平面与温度的统计关系

英文文献摘要：
We study the stability of the estimated statistical relation of global mean temperature and global mean sea-level with regard to data revisions. Using three different model specifications proposed in the literature, we compare coefficient estimates and forecasts using two different vintages of the annual time series. We find that two out of the three models, proposed in [1] and in [2], are very sensitive to the revisions. The magnitude of the estimated coefficient of influence as well as the implied long-term forecasts change drastically between the two data vintages considered. The model proposed in [3], on the other hand, reacts robustly to the revisions.
研究了全球平均气温和全球平均海平面估计统计关系在数据修正中的稳定性。使用文献中提出的三种不同的模型规格，我们比较了使用两种不同年份的年度时间序列的系数估计和预测。我们发现，在[1]和[2]中提出的三种模型中，有两种对修订非常敏感。估计的影响系数和隐含的长期预测的大小在考虑的两个数据年份之间变化很大。另一方面，[3]中提出的模型对修订的反应非常强烈。
