Academy of Mathematics and Systems Science, CAS Colloquia & Seminars：Subsampling for Rare Events Data and maximum sampled conditional likelihood
罕见事件数据 子采样 最大采样 条件似然
2023/5/15
In this talk, we show that the available information about unknown parameters in rare events data is only tied to the relatively small number of cases, which justifies the usage of negative sampling. ...
Sadness, more than other emotions, heightens craving to smoke and likelihood of relapse
Sadness emotions heightens craving smoke likelihood relapse
2020/1/19
What drives a person to smoke cigarettes—and keeps one out of six U.S. adults addicted to tobacco use, at a cost of 480,000 premature deaths each year despite decades of anti-smoking campaigns? What r...
Instability in Antarctic ice projected to increase likelihood of worst-case sea level rise（图）
Instability Antarctic ice projected worst-case sea level rise
2019/10/23
Images of vanishing Arctic ice are jarring, but the region’s potential contributions to sea level rise are no match for Antarctica’s. Now, a study says that instability hidden in Antarctic ice increas...

Jordan faces likelihood severe droughts Stanford researchers
2017/9/19
A new analysis of drought in Jordan – one of the world’s most water-poor countries – suggests that without alternate water sources, better land use and improved water-sharing agreements, the country c...

Model Verification and the Likelihood Principle
Model verification Mis-specification testing Hypothesis testing Likelihood principle Sufficiency principle Evidence
2016/6/13
The likelihood principle (LP) is typically understood as a constraint on any measure of evidence arising from a statistical experiment. It is not sufficiently often noted, however, that the LP assumes...
Piecewise Versus Total Support:How to Deal with Background Information in Likelihood Arguments
likelihood fine-tuning background information observation selection effect total evidence
2016/5/30
The use of the Likelihood Principle as a general tool for assessing rival hypotheses has been criticized for its ambiguous treatment of background information. The LP endorses radically different answ...
Likelihood-based classification of high resolution images to generate the initial topology and geometry of land cover segments
Likelihood-based classification Maximum likelihood classification Geo-information systems
2016/5/20
This paper’s origin is to reach for a way for automatic initiation of shape hypothesis for Model Based Image Analysis (MBIA) in the specific case of agricultural fields. A solution is to start with lo...

2016/1/26
This paper considers the maximum generalized empirical likelihood (GEL) estimation and inference on parameters identified by high dimensional moment restrictions with weakly dependent data when the di...

2016/1/25
We study a marginal empirical likelihood approach in scenarios when the num-ber of variables grows exponentially with the sample size. The marginal empirical likelihood ratios as functions of the para...
