查询词典 negative binomial distribution

The linear trend is determined by binomial logistic regression method. The change-point of the abrupt change during the period of analysis is determined by the nonparametric Mann-Whitney-Pittitt test and the parametric Bayesian analysis approach based on Poisson distribution.

线性变化趋势分析方法採用二项逻辑迴归法，时间序列转折点分析则採用Mann-Whitney-Pittitt无母数检定与以卜瓦松分佈为主体的贝氏转折点分析两种方法判定。

Based on the distance of Kullback-Leibler, this paper give the exact definition of the maximum Kullback-Leibler distance between two different distribution functions and prove that this one has analytic properties such as symmetry, triangle inequality which is the same as the Euclidean distance. By the definition, the maximum Kullback-Leibler distance between some conventional distributions, such as two different binomial distributions, two different normal distributions are obtianed.

在Kullback-Leibler距离的基础上，定义了两个概率分布之间的最大Kullback-Leibler距离，证明了这个距离具有欧式距离的对称性，三角不等式性等分析性质，依照该定义，计算了两个不同的二项分布，两个不同的正态分布等一些常见分布之问的最大Kullback-Leibler距离。

We used NCAR/NCEPT anew analyze data and the method of bilinearity insert to fix on profile distribution of several physical field in the air on observation point and the stream field of 700hPa. We primary discussed the possible mechanism to influence aerosol size distribution.The atmospheric condition of 1000hPa~700hPa level had great influence on aerosol size distribution, and influence on coarse particle mainly below 850hPa level. The horizontal wind velocity of 925hPa level is a primary gene which contributed to coarse particles in the air. Vorticity profile especially below 700hPa level is a key gene to influence diffuse and convergence of local aerosol. The air vertical motion velocity greatly influenced aggregation and remove of aerosol particles. The vertical distribution of air temperature mainly influenced vertical transportation of aerosol.

本文利用分类问题的几何意义直接从数据集出发，按照两类样本点之间的距离关系，分别给出SVM训练集呈圆形、环形、球状、柱状分布的测试算法，为基于数据分布的核选择方法提供了实现的基础。

The major findings include:(1) By using fuel as the base indicator of relative efficiency, we found the following input factors' distribution inefficiency for domestic airlines: The distribution inefficiency of labor and capital input factors differs from airline to airline, and is becoming more severe with time; the distribution inefficiency of other factors does not differ very much among airlines but varies with time. It is inefficient from 1989 to 1995 but becomes more efficient during 1996 to 1997;(2) Airline companies have higher economies of density before 1996, but tend to show a constant return to density in 1997 when considering allocative distortions. The technical efficiency of input factors as a whole has declined after the open-air policy;(3) The costs of airlines are increasing significantly due to their distribution inefficiencies;(4) The instrument variable generated through a quasi price function does not have significant influence on cost; this may imply that airline companies in this time period did not exhibit the phenomena of high-quality high-price.

其主要结论如下：(1)藉由相对燃油分配效率探讨各投入要素之分配扭曲情形发现：劳动和因定投入要素之分配无效率因公司别而有所不同，且随时间而严重，唯民国86年稍有改善；其他要素之分配无效率则较不因公司别而有所不同，但亦随时间发生变化，初期为无效率，在民国85、86年则较具效率；(2)若考虑分配扭曲情形下，国内航空业在民国85年之前具有较高之密度经济，民国86年则趋向固定密度报酬；此整体投入要素之技术效率而官，在天空开放政策后其技术效率随时间变化而下降，但就燃油投入要素平均技术进步率而言，则其技术效率逐年增加且幅度明显；(3)航空公司因分配无效率所造成成本增加的情形相当明显；(4)准价格工具变数对成本之影响并不明显，此可能反映在此期间国内航空公司似乎并未趋向於高品质高价格之现象。

Compared with the discrete distribution, we defined a comparison function for continuous distribution, and pointed out the relationship between the discrete distribution and continuous distribution.

仿照离散分布，定义了连续分布的比较函数，并沟通了离散和连续分布的伴随关系。

As for continuous random variable, the connection of distribution function between random variable and its function -- a new random variable can be obtained first according to the definition of distribution function, then the connection between distribution densities can be obtained by derivation; thus the distribution density is solved.
