摘要

摘要当在某些时间点对几个独立菌落中的增殖细胞进行计数时，通过期望最大化算法获得多类型分支过程参数的最大似然估计。在由具有二叉家谱的马尔可夫分支过程控制的子代分布的情况下，该方法依赖于树的部分知识，产生与利用树的完全知识计算的估计相同的估计。

Expectation maximization estimates of the offspring probabilities in a class of multitype branching processes with binary family trees

ABSTRACT When proliferating cells are counted in several independent colonies at some time points, the maximum likelihood estimates of the parameters of the multitype branching process are obtained trough an expectation maximization algorithm. In the case of an offspring distribution governed by a Markov branching process with binary family trees, this method, relying then on a partial knowledge of the tree, yields the same estimates as those computed with the complete knowledge of the tree.

期刊介绍： Mathematical Population Studies publishes carefully selected research papers in the mathematical and statistical study of populations. The journal is strongly interdisciplinary and invites contributions by mathematicians, demographers, (bio)statisticians, sociologists, economists, biologists, epidemiologists, actuaries, geographers, and others who are interested in the mathematical formulation of population-related questions. The scope covers both theoretical and empirical work. Manuscripts should be sent to Manuscript central for review. The editor-in-chief has final say on the suitability for publication.
