论文摘要
多元正常(MVN)混合模型下的强大估计始终是计算挑战。最近提出的最大伪\ b {eta} -likelihood估计量旨在以最小密度差异(DPD)方法的精神估算MVN混合模型的未知参数,但具有相对简单,更易于的计算算法的较大尺寸。在这封信中,在合理的假设集中,如果MVN混合模型在MVN混合模型的情况下,我们将严格地得出最大伪\ b {eta} -likelihood估计器的存在和弱一致性。
Robust estimation under multivariate normal (MVN) mixture model is always a computational challenge. A recently proposed maximum pseudo \b{eta}-likelihood estimator aims to estimate the unknown parameters of a MVN mixture model in the spirit of minimum density power divergence (DPD) methodology but with a relatively simpler and tractable computational algorithm even for larger dimensions. In this letter, we will rigorously derive the existence and weak consistency of the maximum pseudo \b{eta}-likelihood estimator in case of MVN mixture models under a reasonable set of assumptions.
