Academy of Mathematics and Systems Science, CAS Colloquia & Seminars：Modeling normalcy-dominant ordinal time series: An application to air quality level
正态主导 有序时间序列 建模 空气质量水平
2023/5/10
Inspired by the study of air quality level data, we propose a new model for the normalcy-dominant ordinal time series. The proposed model is based on a new zero-one-inflated bounded Poisson distributi...

More natural dust in the air improves air quality in eastern China
More natural dust air quality eastern China
2017/7/20
Man-made pollution in eastern China's cities worsens when less dust blows in from the Gobi Desert, according to a new study published May 11 in Nature Communications.Yes, you read that correctly: When...
This paper proposes a method of valuing air quality based on differences in
wages among cities. Using an urban location model it is shown that the supply of
labor to any city increases with the real...
