二元均匀反褶积

Bivariate Uniform Deconvolution

Martina Benešová, Bert van Es, Peter Tegelaar

摘要:

在二元均匀反卷积模型中,我们构造了一个密度估计。对于这个模型,我们推导出四个反演公式来表示我们想要根据观测的二元密度估计的二元密度。通过替换观测密度的核密度估计,我们得到四个不同的估计。接下来,我们构造这四个估计量的渐近最优凸组合。扩展的偏差,方差,以及渐近正态性,推导。给出了一些模拟算例。

英文摘要:

We construct a density estimator in the bivariate uniform deconvolution model. For this model we derive four inversion formulas to express the bivariate density that we want to estimate in terms of the bivariate density of the observations. By substituting a kernel density estimator of the density of the observations we then get four different estimators. Next we construct an asymptotically optimal convex combination of these four estimators. Expansions for the bias, variance, as well as asymptotic normality, are derived. Some simulated examples are presented.
