查询词典 hypothesis

Based on the measurement and calculation of Chinese agricultural Total Factor Productivity using the non-parameter Data Envelopment Analysis and Malmquist productivity index approach,the paper has tested the convergence hypothesis of the agricultural TFP growth in China for the transformational period(1978~2005),and this includes the σ convergence,unconditional β convergence and the conditional β convergence.

在利用非参数的DEA曼奎斯特生产率指数方法对中国农业全要素生产率进行求解的基础上，论文运用经济增长收敛理论对农业TFP(Total Factor Produc-tivity)增长在1978~2005年转型期的收敛性情况进行检验，这包括从σ收敛、绝对β收敛到条件β收敛的全面检验。

The testing results of either the augmented Solow model or the endogenous growth model which considered different economic opening degrees both support the conditional convergence hypothesis in most sample sets, while the estimated convergence coefficients of the later are significantly lower than those of the former.

大部分样本中，扩大的Solow模型或考虑不同经济开放程度因素下的内生成长模型，支持条件收敛假说，而后者设算出的收敛系数明显较为低。

However, the actual conditions in the market incompletely support this hypothesis. So, we turn to research the statistic distribution traits of the yield under different market conditions. To develop the investigation on securities' investment combination according to the distribution characters of conditional yield will make its actual application closer to the market facts.

然而，实际的市场情况并不完全支持这种假设，因此，我们转而研究不同市场条件下的收益率统计分布特征，根据条件收益率的分布特征进行投资组合理论研究，将使其实际应用更加贴近市场实际。

This paper uses confirmatory factor analysis and structural equation modeling to measure the hypothesis models brought forward in this paper.

本研究采用验证性因素分析的方式并利用结构方程模式来测量本研究所提出之假说模式。

And this paper provides some positive evidence consistent with Fama s weak Conn efficient market hypothesis.

本文的研究结果支持了弱式有效市场假说。

On the contrary it has disadvantages, such as the complexity of computation and the conservatism of hypothesis tests.

随着计算机硬件技术的发展和计算方法的改善，计算量大的问题正在被逐步解决。

A quite different kind of evidence for my hypothesis is its consilience with evolutionary theory.

对这个假说的另一种证据是，这符合进化论。

The null hypothesis is that the efficient estimator is a consistent and efficient estimator of the true parameters.

2， 如果上述理论逻辑通的话，将内生变量 X 作为解释变量， IV 和其他变量（ X2）作为解释变量，看 IV 是否显著，它应该显著。

Obtain an estimator that is consistent whether or not the hypothesis is true

看一下 P 值，如果 P 小于比如说0.1，或者0.05，那么，说明 IV 回归与原来的回归显著不同，原来的方程的确有内生性问题导致的估计偏误。

A new algorithm, based on uniform acceleration and constant altitude flying mode hypothesis, is presented to estimate the mobile target track according to the measured angular information.

在无测距信息的情况下，根据匀加速运动和等高飞行2个弱条件假设，提出了仅利用测角系统测得的空中机动目标的高低角和方位角进行目标飞行轨迹预测的算法，并对算法进行了仿真测试。

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。
