时间域州域的方法是在现代金融分析的普通途径。经济条件改变时间,飘移功能为一个给定的州的变量取决于时间和价格水平。在这份报纸,工作一致地估计 bivariate 飘移,我们的目的由梳时间的一个新动态综合评估者 -- 并且为估计的州域的方法漂流功能。并且我们建立它的 asymptotic 性质并且说明它由模拟超过一些旧的。
Time-domain state-domain methods are common approaches in modern financial analysis.Economic conditions vary time,drift function depends on time and price level for a given state variable.In this paper,to consistently estimate the bivariate drift function,our purpose a new dynamic integrated estimator by combing time-and state-domain methods for estimating drift function.And we establish its asymptotic properties and illustrates it outperforms some old ones by simulations.
