VQ is easy and tend to realize, HMM can comminute the speech dynamically, it can embody not only the dynamic characteristic but also the stationary characteristic of the speech. GMM is a special HMM, it uses combination of many weighted Gaussian density function to approach the distributing density of speaker characteristic vector in characteristic space, so it is also a good way.

This study examines the effects of allocative distortions on returns to density and input demand in domestic airlines during 1989-1997 by using a non-minimum cost function from the cost efficiency point of view. We generalize a globally concave and flexible cost function by using the symmetric generalized McFadden cost function to accommodate allocative distortions for domestic airlines, and estimating the density economies with and without allocative distortions as well as its effect on cost efficiency.

On the basis of the data obtained from the field observations and wind-tunnel modelling, the calculations and comparisons on probability distribution and density, linear correlation analysis of time series, conditional probability density and so on of wind speeds and directions between various sites are made with the aid of statistical analysis of time series, and changes of these variables with height and representativeness of observation period of meteorological data are also discussed.

本文以现场气象观测和风洞模拟实验数据为基础，通过对时间序列进行的统计分析，计算和比较了各个厂址风速、风向的概率分布、概率密度、时间序列线性相关分析、条件概率密度等，还对它们随高度的变化情况、观测时段代表性等问题进行了讨论。

This paper uses mixture density networks to forecast the time-varying conditional density values of financial time series, and puts forth a new numerical algorithm to calculate Expected Shortfall. The application in Hong Kong Hangseng index approves that Value-at-Risk at high probability levels is accurate, and that it also has good forecasting ability in fluctuation. MDNs can effectively describe the empirical distribution of returns and the volatility mechanism, and is a new model for measuring financial market risk.

基于混合密度网络模型估计金融时间序列的时变条件密度，提出采用数值模拟方法计算Expected Shortfall的新途径，对香港恒生指数的实证研究表明，VaR的预测精度在高端分位点较好，模型评估指标反映出预测效果良好，混合密度网络可以有效地描述收益的经验分布统计特征和波动规律，是一种有效的金融市场风险测量模型。
