查询词典 discrete distribution

In this algorithm, the direction-of-arrival is assumed to be a discrete random variable with a priori probability density function defined on a set of candidate points. Whether or not the secondary sample is required is based on the a posteriori probability distribution of a set of candidate point"s, which can be calculated from the array received signals. And then, the resulting beamformer is a weighted sum of the beamformers pointed at the latest set of point"s, which are combined according to the value of the a posteriori probability for each pointing direction.

在该算法中，期望信号的波达方向被看作是一个定义在若干候选波达方向上的离散随机变量，由阵列接收信号计算出各候选波达方向的后验概率，并将后验概率的分布作为是否需要进行二次采样的判断标准；随后，对各波达方向上的波束成形权值线性加权，便可得到自适应波束成形器，权系数为各候选波达方向的后验概率值。

国际会计准则和我国会计准则基本采用的是"独立观"。"一体观"是将每一中期视为年度会计期间的有机组成部分，是会计年度整体不可分割的一部分，而不是独立的会计期间，中期财务报告中应用的会计估计、成本分配、各递延和应计项目的处理必须考虑到全年将要发生的成本和费用，需要以年度预计活动水平为基础分配至各个中期。

该算法不仅体现了DCT块中各个系数的统计分布，同时也捕捉到它们的空间分布信息，对图像的平移、旋转和尺度变换有一定的鲁棒性。

Weft distribution pattern and its input of fabric with varied weft density ;2. In ordor to weave the varied weft density fabric of which weft distribution pattern is prescribed in sections,the definition field of fabric′s weft density function is divided into continuous and discrete intervals according to the variation characteristics of weft density of fabric.

为织造出分区段设定纬密变化的疏密纬织物，根据织物的纬密变化特点，把织物纬密函数的定义域分成连续区间和离散区间；在此基础上，对于分段连续且可能存在间断点的连续区间，建立了卷取量方程；分析并确定了织物各纬卷取量的解区间，给出了卷取量的求解方法——以解区间足够小为解判据的二分法，并阐明了求解方法在间断点处的有效性；对于由离散点构成的离散区间，给出了区间端点卷取量的取值方法和区间中各纬卷取量的确定方法。

The nonlinearity and discrete gradient inherited in CAViaR model is a conundrum for parameter estimation. We take the asymmetric Laplace distribution with scale parameter as the error process; indicate the variance has a minimum positive value when the scale parameter is a constant, conflicting with the distribution of real financial data. Further we estimate the parameters of indirect TARCH-CAViaR model base on Bayesian framework and Markov chain Monte Carlo method. The optimal scale parameter can also be obtained by Markov chain Monte Carlo method.

CAViaR一般模型中递归分位回归方程的非线性和非连续可微性是参数估计的一个难题，基于含有尺度参数的不对称拉普拉斯分布作为误差过程，指出将尺度参数固定为常数会导致不对称拉普拉斯分布随机变量的方差存在最小正值的限制，与实际金融数据分布不符；进而提出采用贝叶斯分析和马尔科夫链蒙特卡罗模拟方法，估计间接TARCH-CAViaR模型的参数，并可获得尺度参数的合理估计。
