分位数

Following is the main contribution of the dissertation. 1 Based on quartile and first order differential, a new outlier detection algorithm is presented, Experiments show that the method combining with low pass filter can remove gross error and unwanted frequency components.

本文的主要工作与创新点在于： 1）将分位数方法与一阶差分法相结合，提出了一种基于一阶差分的粗差剔除方法，该方法与低通滤波器的结合可以有效去除两相流压力波动信号中的粗大误差以及信号频带以外的频率成分。

The median NIH-SS score and infarct volume for acute stroke patients were 6 (interquartile range : 2 to 13) and 3.4 cc (IQR: 1.1 to 16.6), respectively.

急性脑卒中患者美国国立卫生研究院卒中评分中位数和梗死体分别为6 （四分位数间距：2至13）和3.4毫升（ IQR ：1.1-16.6）。

At catheterization, all patients had elevated intrapericardial pressure (median, 12 mm Hg; interquartile range, 7 to 18) and elevated right atrial and end-diastolic right and left ventricular pressures.

在进行导管插管时，所有病人的心包内压都升高(中位数为 12mmHg，四分位数间距为 7～18mmHg)，右房压以及左室和右室舒张期末压也都升高。

The total pregnant women took part in the urine testing of mercury was 2,190. The mean, median, minimum, maximum, 95%CI were 2.58ug/kg, 1.66ug/kg, 0.01ug/kg, 62.07ug/kg, 2.42-2.74ug/kg respectively, and the quarte range was 1.79ug/kg.

孕妇孕期及其新生儿内环境汞暴露现状本次孕妇尿汞检测总计有效2190例，算术平均值为2.58ug/kg，中位数为1.66ug/kg，最小值为0.01ug/kg，最大值为62.07ug/kg，95％CI为2.42-2.74ug/kg，四分位数间距为1.79ug/kg。

Using panel data of listed companies, this paper analyzes it with a quantile regression approach, then draws a conclusion: the share structure and the capability of emerging interior resources effect the capital structure changeably with the different quantiles respectively. That is, for those conditions with low asset-liability ratio, the sign is positive, on the contrary, the sign is negative.

为此本文尝试着将分位数回归理论引入到回归模型中，通过对我国上市公司的相关数据进行分位数回归分析后发现，不同资产负债率水平下，企业股权结构、企业产生内部资源的能力对资本结构的影响效果不同：低负债率水平下，两者均与债务水平正相关；而高负债率水平下，又均与债务水平负相关。

After pericardiocentesis, the intrapericardial pressure decreased (median value,–5 mm Hg; interquartile range,–5 to 0), whereas right atrial and end-diastolic right and left 9 ventricular pressures, although slightly reduced, remained elevated, with a dip–plateau morphology.

在心包穿刺后，心包内压力下降(中位数为-5mmHg，四分位数间距为-5～0mmHg)，而右房压及左室和右室舒张期末压虽然有轻微下降但仍然较高，形态上表现为倾角-平台状。

As a result, quantile regression method is better than other methods in both measuring systematic risk and nonsystematic risk.

在度量非系统性风险方面，主要应用于度量市场风险，并与利用GARCH模型度量VaR的方法和历史模拟方法进行比较，通过后验测试，结果表明，分位数回归在模拟VaR序列方面更为准确些；而在系统性风险度量方面，无论是根据平均绝对离差指标还是方差指标来看，结果发现利用分位数回归计算的系数要优于普通最小二乘估计和M估计。

Respondentsreported a median of 2550 deliveries per year (interquartilerange 2000, 4000), with 30% delivered by cesarean delivery(IQR 25.5%, 32.5%) and 5% of cesarean deliveries performed undergeneral anesthesia (IQR 4%, 8%).

受访者报告的中位数为2550次分娩/年（四分位数间距 2000 ， 4000 ），其中30 ％为剖宫产（ IQR 25.5 ％， 32.5 ％），5 ％的剖宫产在全身麻醉下进行（ IQR 4 ％， 8 ％）。

Based on the micro data in the Northeast urban labor market in China, the paper regresses the wage equations of male and female at different quantiles and decompose the gender wage gap which come from quantile regression.

文章依据东北城市劳动力市场的微观数据，分别对男性和女性工资方程进行分位数回归，并对分位数回归结果进行性别工资差异分解。

The adjusted population-attributable risk of AMI for the top 3 quartiles compared with the bottom quartile of the dietary risk score was 30%.

与饮食危险评分的第一四分位数相比，后三个四分位数的AMI校正人群归因危险为30％。

The split between the two groups can hardly be papered over.

这两个团体间的分歧难以掩饰。

This approach not only encourages a greater number of responses, but minimizes the likelihood of stale groupthink.

这种做法不仅鼓励了更多的反应，而且减少跟风的可能性。
