On statistical uncertainty in nested sampling
uncertainty Nested sampling Bayesian analysis
2011/3/25
Nested sampling has emerged as a valuable tool for Bayesian analysis, in particular for determining the Bayesian evidence. The method is based on a specific type of random sampling of the likelihood f...
On the Regular Variation of Ratios of Jointly Frechet Random Variables
Regular variation multivariate Frechet distribution spectral
2011/3/18
We provide a necessary and sufficient condition for the ratio of two jointly alpha-Frechet random variables to be regularly varying. This condition is based on the spectral representation of the joint...
Intensive natural distribution as Bernoulli success ratio extension to continuous: enhanced Gaussian, continuous Poisson, and phenomena explanation
Intensive natural distribution as Bernoulli success ratio extension continuous Poisson phenomena explanation
2011/3/18
A new distribution called intensive natural distribution is introduced with the intent of merging statistics and empirical data. Based on the probability derived from the Bernoulli distribution, this ...
党的十六大向全国人民提出了全面建设小康社会的奋斗目标。该目标的提出,不仅反映了我党政策的连续性和稳定性,而且还反映了我们党对小康内涵认识的深化。20世纪90年代惯用的“小康生活”以及世纪之交的“总体小康水平”已改变为今天的“全面小康社会”,其内涵也增加了“六个更加”(即经济更加发展,民主更加健全,科教更加进步,文化更加繁荣,社会更加和谐,人民生活更加殷实)。要加深对全面小康社会的理解和认识,必须明...
用因子分析法分析临床医学中心绩效评价体系的结构效度
探索性 因子分析结构 效度 指标体系
2008/4/28
目的:对构建的临床医学中心绩效评价体系的结构效度进行分析,为评估和进一步完善指标体系提供依据。方法:对已建立的指标体系,用探索性因子分析法进行结构效度分析。结果:因子分析显示,该指标体系的因子组成和重要性依次为学科优势、人才建设、医疗服务、科研能力、基础建设几部分(其前6个因子累计贡献率为90.17%),大多数指标的载荷系数与某个因子内涵相匹配,说明该指标体系的结构效度与专家设想基本...
中国卫生总费用流向调查
流向调查 卫生总费用
2008/1/31
"2005年全国卫生总费用8000多亿。" 怎么得出这个准确数据? "首先卫生总费用筹资来源和分配流向数字要对得上。" 一个国家的医疗卫生全部的资金来自哪里、如何分配、又流向何方?这是认识国情和讨论医改的基础。 在公共卫生机构费用中,公共财政支出仅占50.7%,"致使公共卫生机构职能错位,过度依赖有偿服务,导致公共卫生服务提供不足。" 这是国内最早参与中国卫生总费用计算的哈尔滨医科大学...
