In this article I introduce an alternative method for estimating particulate air pollution mortality concentration-response functions. This method constrains the particulate air pollution mortality concentration-response function to be biologically plausible--that is, a non-decreasing function of the particulate air pollution concentration. Using time-series data from Cook County, Illinois, the proposed method yields more meaningful particulate air pollution mortality concentration-response function estimates with an increase in statistical accuracy.
在本文中，我介绍了一种估计空气中颗粒物污染死亡率浓度-反应函数的替代方法。该方法将空气中颗粒物污染死亡率浓度-反应函数限制为具有生物学合理性——即，它是空气中颗粒物污染浓度的非递减函数。利用伊利诺伊州库克县的时间序列数据，所提出的方法在提高统计准确性的同时，产生了更有意义的空气中颗粒物污染死亡率浓度-反应函数估计值。
