从上面的介绍可以看出，Odds ratio在某种情况下可以作为相对风险的估计，并且作为衡量相关性的量没有使用上的限制。而相对风险和Odds ratio作为相对风险对于某种特定场合和研究有特定的意义，但它的适用范围受限于特定假设。5.例子和SAS Code 考虑下面的例子：下表中包含的数据来自一个日常压力如何影响一个人对于新健康...

oddsratio(18, 20050,205,377054) 于是进一步明确不是R的程序包存在bug,而是方法的不同导致了SAS与R的输出结果存在差异。进一步回过头查看cci 函数的输出结果,结果发现OR的置信区间输出的说明为Exact 95% CI,于是查看cci 函数的选项中默认:exact.ci.or = TRUE,于是果断将该选项修改为:exact.ci.or = FALSE,结果...

and in a similar manner the odds of success in treatment 2 is derived as: therefore, the odds ratio for treatment 1 versus 2 in kth center is exp(β+b 1k - b 2k ). 5. SAS code for performing likelihood ratio test in a 2 × 2 × 2 contingency tables data binomial;...
This work shows how we can use SAS(R) system to implement the proportional odds ratio (POR) model (Siadaty 2004). POR is used to pool results of several studies together in a meta-analysis of diagnostic tests. It generalizescomparison of competing tests when there are two or mor...
统计学统计学的多因素分析里有一个叫“OR”值的是什么意思。大小说明什么odds ratio.就是优势比的意思.具体可以到任何一本流行病学书中查“病例对照
The proportional odds ratio (POR) model was proposed to relax the “OR-homogeneity” assumption. The model accommodates complex missing patterns, and accounts for correlated results. In the model, when comparing two (or more) tests, each test has its own trend of ORs across studies, while th...
In the model, when comparing two (or more) tests, each test has its own trend of ORs across studies, while the trends of two tests are (assumed to be) proportional to each other, the "proportional odds ratio" assumption. We alleviate dilemma of choosing weighting schemes such that do ...
