摘要
考虑用最大似然法和核函数法对于测线调查的密度推定,选用4个核函数、3个最佳带幅宽;分别用2个探知函数生成计算机模拟测线调查数据,对两种密度推定法进行比较研究.
We consider the estimation of biological population density based on line transect data. Maximum likelihood estimate and nonparametric kernel method for the different bandwidths of optimal smoothing parameter and detection functions is employed.A Comparison between two density estinating methods are made and discussed.
