Abstract
在已知母數分配下，微分幾何的估計方法已證明是有效率的。我們將這種 方法推廣到未知母數分配的模型。提出兩種方法來估計位置參數，並由電 腦模擬的結果來比較不同的估計方法。 A geometric approach to estimation of an unknown parameter in parametric model has been shown efficiency. We extend this approach to semi-parametric model in this paper, the location family. We propose two methods of estimating the location parameter and compare them to other estimators by computer simulation.
