在临床研究中,如果根据相同的风险模式将患者分为可管理的数量组,则患者护理决策通常更容易做出。研究人员可以使用基于潜在群体的轨迹建模来估计个人被归类到特定风险模式组的后验概率。虽然这种方法越来越多地被用于临床研究,但目前还没有衡量标准可以用来确定个人的小组分配是否具有高水平的歧视。在这项研究中,我们提出了一个辨别指数,并给出了每个个体被分配到组的概率的可信区间。我们还提出了一种改进的熵形式来衡量区分程度。这两项建议的措施被用来评估青春期少女行为障碍纵向模式的群体分配。
In clinical research, patient care decisions are often easier to make if patients are classified into a manageable number of groups based on homogeneous risk patterns. Investigators can use latent group-based trajectory modeling to estimate the posterior probabilities that an individual will be classified into a particular group of risk patterns. Although this method is increasingly used in clinical research, there is currently no measure that can be used to determine whether an individual’s group assignment has a high level of discrimination. In this study, we propose a discrimination index and provide confidence intervals of the probability of the assigned group for each individual. We also propose a modified form of entropy to measure discrimination. The two proposed measures were applied to assess the group assignments of the longitudinal patterns of conduct disorders among young adolescent girls.
