| 4. | In this dissertation , life - testing with mixture distribution is discussed and problems are solved as follows : 1 本文对混合分布的寿命试验进行了研究,主要解决了下面几个问题: 1 |
| 5. | However , when the life distribution is a mixture distribution , i . e . , there are many reasons cause the products to be failure , which problem has not been studied . but it is more useful in practice 而当产品的寿命分布为一混合分布,即产品具有多个失效机理时的问题,由于其实用性而更具有研究的意义。 |
| 6. | The vq - based approach assumes a gaussian mixture distribution , which fits real - world image data reasonably well . after estimating this distribution through em method , this approach trains optimized vector quantizers to partition data space 该方法使用更适合真实图像库的高斯混合模型描述数据分布,并训练优化的矢量量化器划分数据空间。 |
| 7. | This paper starts with the financial market micro - structure theory . it takes trading - volume as a vital factor in the process of the price adjustment , and quotes the mdh ( mixture distribution hypothesis ) to explain the price - volume relation 本文主要从金融市场微观结构理论出发,把交易量作为影响价格调整过程的一个重要因素,引用混合分布假说( mdh )来解释股票市场的量价关系。 |
| 8. | Based on the mixture distribution hypothesis ( mdh ) theory , the paper conducted an empirical study into the daily liquidity and volatility of three futures , i . e . , bronze , aluminum and natural rubber , and discovered that the trade volume and volatility display a significantly positive correlation , there is a significantly negative correlation between the open interest and volatility , and liquidity ratio and volatility have no significant correlation 摘要根据混合分布假设理论( mdh )等前人研究成果,及对中国期货市场三个主要期货交易品种铜、铝和天然胶期货的日流动性和日波动性的实证研究,可以发现:交易量与波动率有显著的正相关关系,持仓量与波动率有显著的负相关关系;而流动性比率与波动性却并没有显著的关系。 |
| 9. | After reviewing some statistical models proposed to better characterize the host signal in dct , dwt and spatial domain , we describe the statistical property of host signal using gaussian scale mixture distribution , which is more general and flexible . we also present a new method for estimating the parameters of generalized gaussian distribution rapidly 研究了细节分量的统计模型,包括平稳高斯模型、平稳拉普拉斯模型、平稳广义高斯模型、局部平稳的高斯模型和高斯尺度混合模型,提出了一种广义高斯模型中形状参数的快速估计方法。 |
