Estimation of Population Density Function in Line Transect Sampling Method with Detection Functions
Abouzar Bazyari , Narges Mousavi
Abstract:   (741 Views)

In this article, we wish to find and select appropriate estimators for statistical population density function using line transect sampling in the present of detection functions with light and heavy tailed distributions. Also it is shown that how the type of detection function could be effective in selection of the best estimator and then we propose a unbiased estimators that has the lower variance than the existed estimators. the simulation results show that if detection functions have heavy tailed distribution, then the new estimators have least mean square error.

Keywords: Detection function, Line transect sampling, Mean square error, Relative efficiency
