There was no difference in the sensitivity or specificity of the Ectasia Risk Score System in the population from which it was derived and this independent population of ectasia cases and controls.
在此由角膜扩张病例和对照病例构成的独立人群中，角膜扩张风险评分系统的敏感性和特异性没有差别。
The influent factors of rice yield were studied by principal component analysis and stepwise regression analysis. Result indicated, the mainly factor of the influencing yield is that heat, altitude-rainfall, panicle yield and numbers of the kernel. Taking score of the influent factors of the rice yield as independent variables and rice yield as dependent variable, by stepwise regression analysis, a function was derived.
利用主成分分析法和回归分析法分析影响水稻区试品种产量的因子，结果表明，影响产量的主成分因子分别是热量、海拔-雨量、穗重和粒数；利用各因子作为自变量，水稻产量作为因变量，进行逐步回归分析，建立一个产量回归方程。
MAIN OUTCOME MEASURES: Morphology change of spinal cord was detected by light microscope and electronmicroscope, secreted brain-derived neurotrophic factor was measured by immunohistochemistry and PT-PCR, and the combine behavioral score was used to assess the functional recovery of spinal cord. RESULTS: Immunohistochemistry result showed that OECs transplantation could partly reduce the number of apoptosis cells in spinal gray matter, delay cells reduction in spinal white matter, and accelerate the medullary sheath repair and regeneration.
主要观察指标：应用光学显微镜、电子显微镜观察脊髓形态的变化，采用免疫组织化学、PT-PCR 的方法检测脊髓组织脑源性神经营养因子的分泌，以改良的Gale联合行为评分法对脊髓功能进行评定，结果：免疫组织化学检测显示，嗅鞘细胞移植能部分改善大鼠脊髓灰质神经细胞的凋亡程度，延缓白质神经纤维的减少，促进髓鞘的修复与再生。
Each 1 μL site of spinal cord receiving 109 /L OECs at the speed of 1μL/ min. MAIN OUTCOME MEASURES: Morphology change of spinal cord was detected by light microscope and electronmicroscope, secreted brain-derived neurotrophic factor was measured by immunohistochemistry and PT-PCR, and the combine behavioral score was used to assess the functional recovery of spinal cord.

The cutoff score derived from Cluster-analytic method leads to examinee classifications that are most congruent with the external criterion. The cutoff score established by Nedelsky's method produces the highest value of test information function. A similar result is observed by investigating the interjudge reliability of Nedelsky's method and Angoff's method. 414 or more is the optimal number of judges to employ for establishing stable cutoff scores on CET-4 with Nedelsky's method and Angoff's method. 5 The weights obtained by discriminant analysis sorting from largest to smallest are that of Listening, Reading Comprehension, Vocabulary and Structure. 6 There are considerable changes from unweighted context to weighted one among Nedelsky's method and Angoff's method.
Nedelsky 方法产生的测验分界分数显著高于 Angoff 方法产生的测验分界分数。3）三种标准设定方法在三个不同的心理计量学方面各具优势：在与外在效标的一致性程度方面，聚类分析结合边缘组方法最好，Angoff 方法次之，Nedelsky 方法最差；在项目反应理论的测量精度方面，三种方法基本相同，Nedelsky 方法最好，聚类分析结合边缘组方法最差；在概化理论的评分者一致性信度方面，Nedelsky 方法和 Angoff 方法基本相同，Nedelsky 方法略高。4）在 CET-4情境下，运用 Nedelsky 方法和 Angoff 方法，14位或以上专家人数为推荐的最佳专家人数方案。5）通过判别分析得到 CET-4三部分的权重中，听力理解部分被赋予的权重最大、阅读理解部分次之、词汇与语法结构部分最小。6）加权情境下使用标准设定方法得到的测验分界分数较没有加权情境下得到的测验分界分数在与外在效标的一致性程度和评分者一致性信度两方面都有所提高，Angoff 方法较 Nedelsky 方法提高得尤为明显。
Based on the parameter orthogonality transformation, both the modified likelihood ratio test and the modified Score test are derived. The results are an extension of the works of Wei and Hu (1994) and Wei (1995).
