分阶段发展的行为在一个时期可能表现出与其他时期明显不同的变化率。在本文中，回顾了一个用于显示可识别状态的响应的混合效应模型。模型中一个有趣的组件是变更点。实际上，变更点是开发从一个阶段切换到另一个阶段的时间。在混合效应模型中，变化点可以是一个随机系数。这种可能性允许个体在不同的年龄或不同的治疗时间后从一个阶段过渡到另一个阶段。本文详细回顾了两个例子，这两个例子都可以用广泛可用的软件进行估计。
Behavior that develops in phases may exhibit distinctively different rates of change in one time period than in others. In this article, a mixed-effects model for a response that displays identifiable regimes is reviewed. An interesting component of the model is the change point. In substantive terms, the change point is the time when development switches from one phase to another. In a mixed-effects model, the change point can be a random coefficient. This possibility allows individuals to make the transition from one phase to another at different ages or after different lengths of time in treatment. Two examples are reviewed in detail, both of which can be estimated with software that is widely available.
