    Abstract: 在生態統計學中,野生動物數量的估計是一件困難的工作,因為資料的搜集需要耗費大量的金額與時間,
    In ecology research, estimating wildlife abundance
    is usually a difficult work. It may be expensive and time
    consuming to collect enough data for analysing. Besides collecting
    the data, the appropriateness of the analysis depends on whether
    the model assumption is plausible or not. The line transect
    approach had been considered as a convenient approach with minor
    assumptions and it requires relatively less effort in collecting
    data. In the present paper , we investigate the effects of
    additive measurement error and multiplicative measurement error on
    estimating the abundance in a line transect model , respectively .
    We propose estimators that correct biases using method of moments
    and nonparametric density estimation. The simulation result shows
    that these estimators work fine in reducing the biases when
    measurement error is present.
    Key words :Line
    transect model; Additive measurement error; Multiplicative
    measurement error ; Nonparametric density estimation.
