假设检验

Using a variety of statistical methods tested what rate of assets return are not subject to the normal distribution assumption, but leptokurtic distribution, and week data is closer to the normal distribution than daily data.

采用多种统计方法检验了资产收益率并不服从正态分布假设，而是尖峰厚尾分布，且周收益率要比日收益率更接近正态分布。

This nonparametric test was preferred, because no assumptions about the underlying distributions are necessary.

这是首选的非参数检验，因为没有任何假设的基本分布是必要的。

You want the null hypothesis, that the data are normal, to be true.

这个检验中，你不希望拒绝原假设，而希望证明数据是满足正态性的。

The empirical results show that the FIGARCH model based on the skew student-t distribution is better than other distribution on the assumption in estimating the value of the dynamic Var, because it is better to reflect the risk of actual rate of return and it is proved to be better to choose the skew t-distribution model through the Pearson test.

实证结果表明，基于偏态t分布下的FIGARCH模型测算的动态Var值克服了其他分布假设上的不足，能够较好的反映金融收益率的实际风险，最后在该分布下的Pearson吻合度检验也证实了模型分布选择的正确性。

In this we tested in mice the hypothesis that theadministration of infusions of green and white tea and of thearomatic plant Pelargonium purpureum increasesthe total antioxidant capacity of andof selected organs.

在这项研究中我们在老鼠检验的假设绿色和白色茶的注入的管理和的芳香植物天竺葵purpureum增量总抗氧化容量等离子和选择的器官。

An empirical research is taken with data from manufacturing in China to verify aforesaid postulation and compare with overseas practice.

本文利用中国制造业数据，对这一假设进行了实证检验，并利用国外数据进行了比较研究。

We therefore tested the hypothesis that premedication with mirtazapine can reduce preoperative anxiety and PONV.

因而，我们将检验术前予米氮平可减少术前焦虑和 PONV 的假设。

The hypotheses were tested using ordinal probit analysis and data on 2,159 expansions of 25 companies over a period of more than three decades.

我们使用序数概率单位分析和25家公司在三十多年中2159次扩张的数据来检验假设。

The efficient market hypothesis has refutable inference, but the refutability is greatly crippled by Bad-model problems. This means that the overall framework o f testing may be defective and there is a need to relax the assumptions or to be tter define market efficiency .

有效市场假说形式上是可以被证伪的，但坏模型问题的困扰使得证伪过程在技术上不充分，这意味着整个检验框架可能存在缺陷，需要放松假设或对市场有效给出一个更完备的定义。

Fourthly, on the strength of the 165 valid questionnaires which answered by the 165 MNCs' TMT in China, we are using statistic regression techniques such as factor analysis, structural equation model, and path analysis to test these 13 hypotheses.

四、利用165家在华跨国公司的高层管理人员所填写的调查问卷，本文采用因子分析、结构方程模型、路径分析等统计分析方法对相关假设进行了实证检验。

According to the clear water experiment, aeration performance of the new equipment is good with high total oxygen transfer coefficient and oxygen utilization ratio.

曝气设备的动力效率在叶轮转速为120rpm～150rpm时取得最大值，此时氧利用率和充氧能力也具有较高值。

The environmental stability of that world - including its crushing pressures and icy darkness - means that some of its most famous inhabitants have survived for eons as evolutionary throwbacks, their bodies undergoing little change.

稳定的海底环境─包括能把人压扁的压力和冰冷的黑暗─意谓海底某些最知名的栖居生物已以演化返祖的样态活了万世，形体几无变化。
