Abstract

A model in the form of a Markov chain is constructed to mimic variations in the human sex ratio. It is illustrated by simulation. The equilibrium distribution is shown to be a simple modification of the binomial distribution. This enables an easy calculation of the variation in sex ratio which could be expected in small populations.

性别比例演变的马尔可夫链模型。

我们构建了一个马尔科夫链形式的模型来模拟人类性别比率的变化。并通过模拟加以说明。平衡分布被证明是对二项分布的简单修改。这样就可以很容易地计算出在小规模人群中可能出现的性别比例变化。
