abuse as a motivating example to demonstrate that the proposed model can characterize the time-varying effect of negative peer influences on alcohol use in a way that is more consistent with the developmental theory and existing literature, in comparison with the linear time-varying effect model. ...
This article considers the problem of examining time-varying causal effect moderation using observational, longitudinal data in which treatment, candidate moderators, and possible confounders are time varying. The structural nested mean model (SNMM) is used to specify the moderated time-varying causal ...
In particular, the new procedure considers the shared random-effect model and assumes a time-varying coefficient for the latent variable, allowing a flexible way of modeling longitudinal outcomes while adjusting their association with observation times. Estimating equations are developed for parameter ...
This thesis is concerned with presenting and developing modeling approaches which allow for a time-varying effect of covariates by using time-varying coefficients. The different approaches are compared in simulation studies. Thereby, we ...
Marginal structural models (MSM) provide a powerful tool for estimating the causal effect of a treatment. These models, introduced by Robins, model the mar... dLMJ Van,ML Petersen,MM Joffe - 《International Journal of Biostatistics》 被引量: 164发表: 2005年 History-Adjusted Marginal Structural...
The flood safety of dams is subjected to various stochastic factors.With the elapse of time,those factors having negative impact on the flood control safety are of obvious time-varying characteristics.The time-varying characteristics of flood control of dams due to this effect,both the impact of ...
The time-varying effect model (TVEM) handles EMA data challenges and addresses unique questions about the time-varying effects. Methods: Generalized TVEM was applied to EMA data from a smoking cessation study to investigate a "time-varying lagged" effect of negative affect on high smoking urges...

M-Model is validated by a subjective experiment. The model indicates that time-varying quality with extremely high frequency does not affect perceived quality at all. In addition, we observed that the recency effect influences not only the perceived overall quality but also the perceived ...
