This chapter reviews the advantages and problems of the log likelihood ratio test, and gives real and hypothesized data examples supporting its better sensitivity. We do hope that the chapter will stimulate researchers to more often apply this test....
似然比检验是对较小模型与更复杂的模型的充分性的检验。 检验的原假设指出,较小的模型为数据提供了与较大模型一样好的拟合。 如果拒绝了原假设,那么替代的较大模型提供了比较小模型的显着改进。 要使用似然比检验,零假设模型必须是嵌套在其中的模型,即替代假设模型的特殊情况。 例如,定标恒等式结构是复合对称结构...
shape of the likelihood curve describes the degree of support for a particular value of the heritability. In a Bayesian context, the posterior distribution of heritability fulfills a similar role. Also, for example, a likelihood ratio test can be used to check whether a nonadditivegeneticcomponent...

The numbers of OS and PFS events in the whole patient cohort and in the investigated subgroups are shown in Additional file 1. Statistical analyses All the data were analyzed with SPSS statistics software (Armonk, NY, USA), version 27. Differences between the groups were analyzed with the Chi...
All data was normally distributed as analyzed with SPSS version 20 (IBM SPSS 244 Inc., Chicago, IL). A 2 × 2 ANOVA was conducted to compare the demographic data and the data of the test battery between the RTS group and the NO-RTS groups. In addition, paired sample t-tests were use...
Differences in being employed or not 3 years later with respect to job change were investigated using Pearson’s chi-squared test. Logistic regression analysis was used to calculate the likelihood (odds ratio (OR)) that individuals sick listed for more than 180 days were employed 2, 3 and 4...
SPSS version 23.0 (IBM) was used. p values < 0.05 were considered significant. Results Patient characteristics Baseline characteristics of the 299 RA patients are pre- sented in Table 1. The median symptom duration at first presentation was 15 weeks (interquartile range (IQR) 8– 32) and, ...
An ROC curve was determined using SPSS. The slope of the ROC curve, which is the likelihood ratio for each value of PsIgE, was determined by differentiated the ROC curve and used to convert sIgEs to likelood ratios. Results PsIgE ranged from 0 to 23. There were 33 negative and 25 ...
