查询词典 sample size

Study limitations include small sample size, exclusion of several potentially eligible children because of medication-related drowsiness or refusal to participate, limited ability to generalize the results, and testing of some children more than once resulting in a learning effect or decreased pain due to healing. Older children found the game too simple and therefore not as distracting as the younger children reported it to be. Because the VR equipment was not waterproofed, pain responses could not be determined through an entire dressing change, including during wound debridement in the bathroom.

这项试验的限制因素，包括样本数很小、排除许多潜在合适的儿童，因为药物相关的嗜睡或是拒绝参与试验，而限制了这个试验结果的普遍性，而且对许多儿童进行一次以上的试验会造成一种记忆效果，或是因为复原而减少疼痛；年龄较大的儿童觉得这些游戏太过简单，因此不像对年龄较小的儿童一样，那麼地吸引人；且因为VR装备不是防水的，因此疼痛反应不能在换衣服时评估，包括於浴室时清创时。

"But in the end it has the same problem fossils have--the sample size is very small."

&但是，到头来它还是面临同样的问题，化石样品的规模实在太小了。&

Randomization, blocking, sample size determination, factorial designs, 2^p full and fractional factorials, response surfaces, Latin squares, split plots, Taguchi designs.

实验设计：实验设计：随机化，区组设计，抽样规模的确定，析因设计。完全的和部分的析因设计，反应曲面法，拉丁方，裂区法，Taguchi 设计。

While most people realise it is hard to calculate VAR using internal data alone (because of the small sample size), many are unaware that because op risk is characterised by fat-tailed distributions, even the expected loss cannot be estimated using just internal loss data.

虽然大多数人认识到单单使用内部数据很算计算出风险值，可很多人没认识到这一点：因为操作风险的特征是厚尾分布，要是单单使用内部损失数据，连预期损失都无法估计出来。

Fixing the variation,the rate of erroneous judgment will get smaller if the sample size gets larger.

为严格控制Ⅰ类错误起见，本研究取相同情形下P_的最大值。

Linear Discriminant Analysis is one of the most popular linear projection techniques for feature extraction. The major drawback of applying LDA is that it often encounters the Small Sample Size problem. Besides, their optimization criteria is not directly related to the classification accuracy.

摘要线性判别分析是一种较为普遍的线性特征提取方法，它的主要缺点是在应用时经常遇到小样本问题，同时其准则函数并不与识别率直接相关。

BACKGROUND: Gene microarray data has small sample size and large numbers of variates.

摘要背景：微阵列数据的特点是样本含量小，而变量数多达上万个。

Further trial of larger sample size and screening for other exons should he conducted to investigate the relationship between the ABCB4 gene mutation and the occurrence of ICP in the Chinese population.

BCB4基因的突变与中国人ICP发病的相关性仍应进行更大样本的研究和其他外显子的筛查。

Finally, notes Weinberg, who was not involved in the new study but is familiar with its design and results, the lack of effectiveness could have been due in part to the trial's small sample size.

最后，没有参与这项新研究却熟悉其设计和结果的温伯格博士指出，疫苗的失效可以部分归因于试验的样本数量太小。

Protocols must include appropriate statistical sections which define the efficacy parameters upon which the trial sample size and decision criteria are based.

协议必须包括适当的统计学章节，介绍如何以实验样本大小和决策标准为基础来界定疗效参数。
