差异性的统计推断方法及其应用（张维、李启寨）
差异性 统计推断方法 应用
2023/2/22
差异性分析是生物医学研究中的一个重要问题。它旨在通过比较两组或多组样本数据之间的差异来识别影响复杂疾病或性状的基因、生物通路、微生物等。针对人类微生物组和水稻耐寒性的差异性分析问题，提出了自适应的分组聚合检验方法，给出了统计显著性的快速算法及其统计性质，利用多尺度分析方法有效地整合水稻耐寒性的两个性状，提出了群体分层校正方法并将其应用到水稻耐寒性的数据中，发现并验证了与水稻耐寒性相关联的基因COL...

2018/9/30
在广义诱导有序加权对数平均算子(IGOWLA算子)的基础上,引入指数支撑度以及构建了一种基于支撑度的IGOWLA 算子的最优组合预测模型,并对该模型的预测精度、优性及非劣性给出定义.实例分析表明,该组合预测模型优于传统的组合预测模型,能够充分利用各个单项预测方法的信息并能提高预测精度,是一种优性组合预测.
Error probability analysis in quantum tomography: a tool for evaluating experiments
Error probability analysis quantum tomography tool for evaluating experiments
2010/12/15
We expand the scope of the statistical notion of error probability, i.e., how often large deviations are observed in an experiment, in order to make it directly applicable to quantum tomography. We ve...

2010/12/8
A complete characterization of Wishart distributions on the cones of positive semi-definite matrices is provided in terms of a description of their maximal parameter domain.
The coherent states for a set of quadratic Hamiltonians in the trap regime are constructed.
A matrix technique which allows to identify directly the creation and annihilation operators will be presen...
Higher order statistics in the annulus square billiard: transport and polyspectra
Higher order statistics annulus square billiard: transport polyspectra
2010/12/15
Classical transport in a doubly connected polygonal billiard, i.e. the annulus square billiard, is considered. Dynamical properties of the billiard flow with a fixed initial direction are analyzed by ...
