提出了一种估计截断点的新方法,该方法可最小化傅立叶级数密度估计器的均方积分误差 (MISF)。新方法与 Akaike (1974) 用于估计统计模型维数的 AIC 过程的相似性提出了选择截断点的第二种方法。结果表明,这两种新方法都可以对基础密度进行一致的估计。模拟研究表明,对于某些密度函数,新方法是对原始方法的改进。 Kronmal 和 Tarter (1968) 的方法。
A new method of estimating the truncation point which minimizes the mean integrated squared error (MISF) of a Fourier series density estimator is proposed The similarity of the new method to Akaike’s (1974) AIC procedure for estimating the dimension of a statistical model suggests a second method of choosing a truncation point.It is shown that both of the new methods lead to consistent estimation of the underlying density.A simulation study indicates that for certain density functions the new methods are an improvement over the original method of Kronmal and Tarter (1968).
