First, heart rate variability, blood pressure variability and spontaneous baroreflex sensitivity were analyzed among 89 healthy civil flying personnel by using conventional AR spectral analysis and sequence method respectively.

方法先对 89名健康民航飞行人员的心率变异性与血压变异性的谱分析及压力反射敏感性数据进行主成分分析，再利用多重回归分析得出心血管年龄的估计方程。

In this dissertation , the methods of prediction and parameters\' estimation based on stationary multivariate autoregressive models AR(p are studied systematically. Some properties of these methods are formulized.In the first part, it introduce some basal conceptions about multidimensional stationary time series, contained the estimation and property of mean vector and auto-covariance function. Then the stable condition of multidimensional AR models are discussed.

Secondly, the subsample study based on the linear regression model shows that although taking the instability of economic structure into account, the estimation of exchange premium to the change of spot exchange rate is obviously negative, which meas the outlier or breakpoint is not the reason that empirical research refuses the efficiency of the American and the Japanese foreign exchange markets.

其次，基于线性回归模型的子样本研究表明，即使考虑了经济结构突变，远期汇水对即期汇率变动的估计仍显著的为负值，即统计上数据异常和结构突变并不是拒绝美元和日元外汇市场有效的原因，因此我们需要去探讨理论本身的缺陷和不足。
