自回归和交叉滞后模型已被广泛用于理解社会和行为科学中二元相称结果之间的关系，但在二元非相称（例如混合二元和连续）结果同时建模方面开展的工作并不多。我们开发了一种基于似然的方法，将普通自回归和交叉滞后模型与混合模型框架中共享的特定受试者随机效应结合起来，对两个相关的纵向非相称结果进行建模。我们的模型对交叉滞后和自回归效应的估计与单变量广义线性模型的估计相一致，均方误差更小。在提出的模型中纳入受试者特定的随机效应，解释了受试者之间的可变性，这些可变性是由被省略的和/或不可观察的，但可能解释的受试者水平预测因子引起的。我们的模型并不局限于每个受试者的事件数量相等的情况，它可以扩展到不同类型的双变量结果。我们将该模型应用于具有复杂依赖关系和采样数据结构的生态瞬时评价研究。具体来说，我们研究避孕套的使用和性满意度之间的依赖关系是基于一项性传播感染的纵向研究报告的数据。我们发现这两个结果之间存在负的交叉滞后效应，而每个结果内部存在正的自回归效应。版权所有©2017 John Wiley & Sons， Ltd
Autoregressive and cross‐lagged models have been widely used to understand the relationship between bivariate commensurate outcomes in social and behavioral sciences, but not much work has been carried out in modeling bivariate non‐commensurate (e.g., mixed binary and continuous) outcomes simultaneously. We develop a likelihood‐based methodology combining ordinary autoregressive and cross‐lagged models with a shared subject‐specific random effect in the mixed‐model framework to model two correlated longitudinal non‐commensurate outcomes. The estimates of the cross‐lagged and the autoregressive effects from our model are shown to be consistent with smaller mean‐squared error than the estimates from the univariate generalized linear models. Inclusion of the subject‐specific random effects in the proposed model accounts for between‐subject variability arising from the omitted and/or unobservable, but possibly explanatory, subject‐level predictors. Our model is not restricted to the case with equal number of events per subject, and it can be extended to different types of bivariate outcomes. We apply our model to an ecological momentary assessment study with complex dependence and sampling data structures. Specifically, we study the dependence between the condom use and sexual satisfaction based on the data reported in a longitudinal study of sexually transmitted infections. We find negative cross‐lagged effect between these two outcomes and positive autoregressive effect within each outcome. Copyright © 2017 John Wiley & Sons, Ltd.
