First, we obtain the empirical Bayesian estimator of the scale parameter for the double exponential distribution based on LINEX loss function and the convergence rate of the estimate.
首先利用非对称的LINEX损失函数对双指数分布族刻度参数进行了经验贝叶斯估计，并讨论了该估计的性质，给出了收敛速度。
This kind of coupling relation takes on a double-exponential function changing law, and the evolutive track of the interaction between urbanization and eco-environment is a double-exponential curve.
这种耦合关系在其演化周期内呈现出双指数函数的变化规律，其耦合演化轨迹是一条双指数曲线；
