Adaptive kernel function using line transect sampling

Abstract

The estimation of f(0) is crucial in the line transect method which is used for estimating population abundance in wildlife survey’s. The classical kernel estimator of f(0) has a high negative bias. Our study proposes an adaptation in the kernel function which is shown to be more efficient than the usual kernel estimator. A simulation study is adopted to compare the performance of the proposed estimators with the classical kernel estimators.
