摘要
Abstract
We consider the estimation of biological population density based on line transect data.Nonparametric kernel method for the different bandwidths of optimal smoothing parameters, detection functions and kernel functions are applied.In case of different detection function,using optimal bandwidths and different kernel function to do density estimate, getting distance data of line transect by numerical simulation through computer, we evaluate the estimate value by RRMSE, to verify the adaptability among the three combinations.关键词
