We derive an improved unimodality criteria for the elliptical multivariate leptokurtic-normal (MLN) distribution. For finite mixtures of MLN, we prove identifiability. Then we provide a new estimation algorithm and show improvement over existing methods.

振兴多元椭圆尖峰正态分布及其在基于模型的聚类中的应用

我们推导出椭圆多变量尖峰正态 (MLN) 分布的改进单峰标准。对于 MLN 的有限混合,我们证明了可识别性。然后我们提供了一种新的估计算法,并展示了对现有方法的改进。
