One method to analyze bounded variable of this paper is "The Bounded Unit Root" which provided by Cavaliere (2005), and the other is using Gibbs sampling simulation and trying to recover the part of hidden variables. We would examin some empirical problems that has often been tackled in the literature and we give three time series which include Danish kron/Deutshe mark, Belgium Franc/ Deutshe mark, and Japan 1 mouth interbank interest rate for examples.

本文利用Cavaliere (2005)所提出的限制下单根检定与Gibbs sampling将潜在变数还原的方法，探讨当资料受到限制时的单根检定问题，并以丹麦克朗与比利时法郎兑德国马克的双边汇率以及日本同业间一个月期拆款利率为例，比较其与传统单根检定的结果有何异同。

More qualitative than many sociologists, Lamont nonetheless does a great deal of empirical analysis.

An empirical distribution ratio model for Am and lanthanides in HBTMPDTP extraction has been established and a method of process parameters calculation has been proposed.

Since Leptokurtosis, skewness and fat-tail are always used to depict market risk, this paper introduces the improved Laplace distribution to risk management of stock portfolio. Empirical results show, improved Laplace distribution and asymmetric Laplace distribution are similar for estimating Leptokurtosis, while improved Laplace distribution is better for estimating skewness.In order to analyze the correlation between return distribution and volatility, the thesis uses ARCH-M Models to simulate the return series of China's Stock Market and developed markets ao as to discover the relation between investment return and time-varying risk.

对尖峰、厚尾、偏态的刻画有助于正确估计市场风险，本文将改进型Laplace分布引入到股票组合的风险管理中，实证结果发现，改进型Laplace分布和非对称Laplace分布对尖峰、厚尾的刻画效果接近；而非对称Laplace分布对负偏性考察不足，改进型Laplace分布的拟合结果能够准确地反映股指收益的负偏态，这也正是改进型Laplace分布相对于传统的非对称Laplace分布的优势所在。
