查询词典 estimate

The estimate is 10 times smaller than one estimated by Kyte et al.(1988),but it is close to the realistic situation of the Eltanin impact event,and it is a more reasonable lower limit estimation on...

这比Kyte 等人（1988）估计的质量小了10 倍，然而它更接近埃尔塔宁小行星撞击事件的实际情况，可以作为埃尔塔宁小行星质量下限和半径下限更合理的估计值。

When the signal sources have different cycle frequencies, a method to estimate the optimal time lag is presented. It solves the severe problem that the conventional Cyclic MUSIC requires knowing the optimal time lag in computing the cyclic correlation matrix. A method of two-step search for DOA estimation by employing an interleaving technique and a Joint Estimation Strategy is developed to overcome the inadequency of signal sources with the same cycle frequency having no optimal time lag.

当信源的循环频率各不相同时，提出了一种估计最佳延时的方法，解决了传统Cyclic MUSIC算法计算循环相关矩阵需要已知最佳延时的问题；为克服多个具有相同循环频率信源不存在最佳延时的不足，利用交错技术和联合估计策略，提出了两步搜索估计DOA的方法。

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。
