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.
An empirical method is put forward to estimate diffusion parameters in complex terrain in the light of the modelling experiments and is verified by the data from other sites.
