Generalized structured component analysis (GSCA) is a multivariate method for examining theory-driven relationships between variables including components. GSCA can provide the deterministic component score for each individual once model parameters are estimated. As the traditional GSCA always standardizes all indicators and components, however, it could not utilize information on the indicators' scale in parameter estimation. Consequently, its component scores could just show the relative standing of each individual for a component, rather than the individual's absolute standing in terms of the original indicators' measurement scales. In the paper, we propose a new version of GSCA, named convex GSCA, which can produce a new type of unstandardized components, termed convex components, which can be intuitively interpreted in terms of the original indicators' scales. We investigate the empirical performance of the proposed method through the analyses of simulated and real data.

广义结构成分分析(GSCA)是一种多变量方法,用于研究包括成分在内的变量之间的理论驱动关系。在估算出模型参数后,GSCA 可以提供每个个体的确定性成分得分。然而,由于传统的 GSCA 总是将所有指标和成分标准化,因此在参数估计时无法利用指标的尺度信息。因此,其成分得分只能显示每个个体在某一成分中的相对地位,而不是个体在原始指标测量尺度中的绝对地位。在本文中,我们提出了一种新版本的 GSCA,称为凸 GSCA,它可以产生一种新型的非标准化分量,称为凸分量,这种分量可以直观地从原始指标量表的角度进行解释。我们通过对模拟数据和真实数据的分析,研究了所提方法的实证性能。

Response process data from computer-based problem-solving items describe respondents' problem-solving processes as sequences of actions. Such data provide a valuable source for understanding respondents' problem-solving behaviors. Recently, data-driven feature extraction methods have been developed to compress the information in unstructured process data into relatively low-dimensional features. Although the extracted features can be used as covariates in regression or other models to understand respondents' response behaviors, the results are often not easy to interpret since the relationship between the extracted features, and the original response process is often not explicitly defined. In this paper, we propose a statistical model for describing response processes and how they vary across respondents. The proposed model assumes a response process follows a hidden Markov model given the respondent's latent traits. The structure of hidden Markov models resembles problem-solving processes, with the hidden states interpreted as problem-solving subtasks or stages. Incorporating the latent traits in hidden Markov models enables us to characterize the heterogeneity of response processes across respondents in a parsimonious and interpretable way. We demonstrate the performance of the proposed model through simulation experiments and case studies of PISA process data.

基于计算机的问题解决项目的反应过程数据将受访者的问题解决过程描述为一系列行动。这些数据为了解受访者解决问题的行为提供了有价值的来源。最近,已经开发了数据驱动的特征提取方法来将非结构化过程数据中的信息压缩成相对低维的特征。尽管提取的特征可以作为回归或其他模型中的协变量来理解受访者的反应行为,但由于提取的特征和原始反应过程之间的关系往往没有明确定义,因此结果通常不容易解释。在本文中,我们提出了一个统计模型来描述响应过程以及它们在受访者中的变化。所提出的模型假设响应过程遵循隐马尔可夫模型,给定被调查者的潜在特征。隐马尔可夫模型的结构类似于解决问题的过程,隐藏状态被解释为解决问题的子任务或阶段。将潜在特征纳入隐马尔可夫模型使我们能够以一种简洁和可解释的方式来表征受访者之间反应过程的异质性。我们通过模拟实验和PISA过程数据的案例研究来证明所提出的模型的性能。

The key assumption of conditional independence of item responses given latent ability in item response theory (IRT) models is addressed for multistage adaptive testing (MST) designs. Routing decisions in MST designs can cause patterns in the data that are not accounted for by the IRT model. This phenomenon relates to quasi-independence in log-linear models for incomplete contingency tables and impacts certain types of statistical inference based on assumptions on observed and missing data. We demonstrate that generalized residuals for item pair frequencies under IRT models as discussed by Haberman and Sinharay (J Am Stat Assoc 108:1435-1444, 2013. https://doi.org/10.1080/01621459.2013.835660 ) are inappropriate for MST data without adjustments. The adjustments are dependent on the MST design, and can quickly become nontrivial as the complexity of the routing increases. However, the adjusted residuals are found to have satisfactory Type I errors in a simulation and illustrated by an application to real MST data from the Programme for International Student Assessment (PISA). Implications and suggestions for statistical inference with MST designs are discussed.

在项目反应理论(IRT)模型中,针对多级自适应测试(MST)设计,提出了在给定潜在能力的情况下,项目反应条件独立性的关键假设。MST设计中的路由决策可能导致IRT模型未考虑的数据模式。这种现象与不完整列联表的对数线性模型的准独立性有关,并影响基于对观测到和缺失数据的假设的某些类型的统计推断。我们证明了Haberman和Sinharay(J Am Stat Assoc 108:1435-14442013)讨论的IRT模型下项目对频率的广义残差。https://doi.org/10.1080/01621459.2013.835660)不适用于未经调整的MST数据。调整取决于MST设计,并且随着路由的复杂性增加,调整可能很快变得不重要。然而,在模拟中发现调整后的残差具有令人满意的I型误差,并通过国际学生评估计划(PISA)对真实MST数据的应用进行了说明。讨论了MST设计对统计推断的启示和建议。

Going Deep in Diagnostic Modeling: Deep Cognitive Diagnostic Models (DeepCDMs). 深入诊断模型:深度认知诊断模型(DeepCDMs)。
IF 2.9 2区 心理学 Q1 MATHEMATICS, INTERDISCIPLINARY APPLICATIONS Pub Date : 2024-03-01 Epub Date: 2023-12-11 DOI: 10.1007/s11336-023-09941-6

Cognitive diagnostic models (CDMs) are discrete latent variable models popular in educational and psychological measurement. In this work, motivated by the advantages of deep generative modeling and by identifiability considerations, we propose a new family of DeepCDMs, to hunt for deep discrete diagnostic information. The new class of models enjoys nice properties of identifiability, parsimony, and interpretability. Mathematically, DeepCDMs are entirely identifiable, including even fully exploratory settings and allowing to uniquely identify the parameters and discrete loading structures (the " Q -matrices") at all different depths in the generative model. Statistically, DeepCDMs are parsimonious, because they can use a relatively small number of parameters to expressively model data thanks to the depth. Practically, DeepCDMs are interpretable, because the shrinking-ladder-shaped deep architecture can capture cognitive concepts and provide multi-granularity skill diagnoses from coarse to fine grained and from high level to detailed. For identifiability, we establish transparent identifiability conditions for various DeepCDMs. Our conditions impose intuitive constraints on the structures of the multiple Q -matrices and inspire a generative graph with increasingly smaller latent layers when going deeper. For estimation and computation, we focus on the confirmatory setting with known Q -matrices and develop Bayesian formulations and efficient Gibbs sampling algorithms. Simulation studies and an application to the TIMSS 2019 math assessment data demonstrate the usefulness of the proposed methodology.

认知诊断模型(CDMs)是一种离散潜变量模型,在教育和心理测量中非常流行。在这项工作中,基于深度生成模型的优势和可识别性的考虑,我们提出了一个新的 DeepCDMs 系列,以寻找深度离散诊断信息。这一类新模型具有良好的可识别性、简约性和可解释性。在数学上,DeepCDMs 是完全可识别的,甚至包括完全探索性的设置,并允许唯一识别生成模型中所有不同深度的参数和离散负载结构("[公式:见正文]-矩阵")。从统计学角度看,DeepCDMs 是简洁的,因为它们可以使用相对较少的参数来表达数据模型,这要归功于深度。实际上,DeepCDM 是可解释的,因为收缩阶梯状的深度架构可以捕捉认知概念,并提供从粗粒度到细粒度、从高层次到细节的多粒度技能诊断。在可识别性方面,我们为各种 DeepCDM 建立了透明的可识别性条件。我们的条件对多个[公式:见正文]矩阵的结构施加了直观的约束,并启发了一个生成图,当深入时,潜在层越来越小。在估计和计算方面,我们将重点放在已知[公式:见正文]-矩阵的确证设置上,并开发了贝叶斯公式和高效的吉布斯采样算法。模拟研究和对 TIMSS 2019 数学评估数据的应用证明了所提方法的实用性。

Nodal Heterogeneity can Induce Ghost Triadic Effects in Relational Event Models. 节点异质性可诱发关系事件模型中的幽灵三联效应

Temporal network data is often encoded as time-stamped interaction events between senders and receivers, such as co-authoring scientific articles or communication via email. A number of relational event frameworks have been proposed to address specific issues raised by complex temporal dependencies. These models attempt to quantify how individual behaviour, endogenous and exogenous factors, as well as interactions with other individuals modify the network dynamics over time. It is often of interest to determine whether changes in the network can be attributed to endogenous mechanisms reflecting natural relational tendencies, such as reciprocity or triadic effects. The propensity to form or receive ties can also, at least partially, be related to actor attributes. Nodal heterogeneity in the network is often modelled by including actor-specific or dyadic covariates. However, comprehensively capturing all personality traits is difficult in practice, if not impossible. A failure to account for heterogeneity may confound the substantive effect of key variables of interest. This work shows that failing to account for node level sender and receiver effects can induce ghost triadic effects. We propose a random-effect extension of the relational event model to deal with these problems. We show that it is often effective over more traditional approaches, such as in-degree and out-degree statistics. These results that the violation of the hierarchy principle due to insufficient information about nodal heterogeneity can be resolved by including random effects in the relational event model as a standard.

时态网络数据通常被编码为发送方和接收方之间有时间戳的交互事件,例如共同撰写科学文章或通过电子邮件进行通信。为了解决复杂的时间依赖性带来的具体问题,人们提出了许多关系事件框架。这些模型试图量化个人行为、内生和外生因素以及与其他个人的互动是如何随着时间的推移改变网络动态的。确定网络中的变化是否可归因于反映自然关系倾向(如互惠或三方效应)的内生机制往往是令人感兴趣的。建立或接受联系的倾向也可能(至少部分地)与参与者的属性有关。网络中的节点异质性通常是通过加入特定行为者或二元协变量来建模的。然而,在实践中要全面捕捉所有个性特征是很困难的,甚至是不可能的。不考虑异质性可能会混淆关键变量的实质性影响。这项研究表明,如果不考虑节点层面的发送者和接收者效应,就会诱发幽灵三元效应。我们提出了关系事件模型的随机效应扩展来解决这些问题。我们的研究结果表明,这种方法通常比更传统的方法(如内度和外度统计)更有效。这些结果表明,在关系事件模型中加入随机效应作为标准,可以解决由于节点异质性信息不足而导致的违反层次原则的问题。

Restricted latent class models (RLCMs) provide an important framework for diagnosing and classifying respondents on a collection of multivariate binary responses. Recent research made significant advances in theory for establishing identifiability conditions for RLCMs with binary and polytomous response data. Multiclass data, which are unordered nominal response data, are also widely collected in the social sciences and psychometrics via forced-choice inventories and multiple choice tests. We establish new identifiability conditions for parameters of RLCMs for multiclass data and discuss the implications for substantive applications. The new identifiability conditions are applicable to a wealth of RLCMs for polytomous and nominal response data. We propose a Bayesian framework for inferring model parameters, assess parameter recovery in a Monte Carlo simulation study, and present an application of the model to a real dataset.

Generalized structured component analysis (GSCA) is a structural equation modeling (SEM) procedure that constructs components by weighted sums of observed variables and confirmatorily examines their regressional relationship. The research proposes an exploratory version of GSCA, called exploratory GSCA (EGSCA). EGSCA is analogous to exploratory SEM (ESEM) developed as an exploratory factor-based SEM procedure, which seeks the relationships between the observed variables and the components by orthogonal rotation of the parameter matrices. The indeterminacy of orthogonal rotation in GSCA is first shown as a theoretical support of the proposed method. The whole EGSCA procedure is then presented, together with a new rotational algorithm specialized to EGSCA, which aims at simultaneous simplification of all parameter matrices. Two numerical simulation studies revealed that EGSCA with the following rotation successfully recovered the true values of the parameter matrices and was superior to the existing GSCA procedure. EGSCA was applied to two real datasets, and the model suggested by the EGSCA’s result was shown to be better than the model proposed by previous research, which demonstrates the effectiveness of EGSCA in model exploration.

广义结构化成分分析(GSCA)是一种结构方程建模(SEM)程序,它通过观察变量的加权和来构建成分,并确认它们之间的回归关系。本研究提出了一种探索性的 GSCA 版本,称为探索性 GSCA(EGSCA)。EGSCA 类似于探索性 SEM(ESEM),是一种基于探索性因子的 SEM 程序,它通过参数矩阵的正交旋转来寻求观察变量与成分之间的关系。首先说明了正交旋转在 GSCA 中的不确定性,为所提出的方法提供了理论支持。然后介绍了整个 EGSCA 程序,以及专门用于 EGSCA 的新旋转算法,该算法旨在同时简化所有参数矩阵。两项数值模拟研究表明,带有以下旋转算法的 EGSCA 成功地恢复了参数矩阵的真实值,优于现有的 GSCA 程序。将 EGSCA 应用于两个真实数据集,结果表明 EGSCA 提出的模型优于之前研究提出的模型,这证明了 EGSCA 在模型探索方面的有效性。

Optimal treatment regimes (OTRs) have been widely employed in computer science and personalized medicine to provide data-driven, optimal recommendations to individuals. However, previous research on OTRs has primarily focused on settings that are independent and identically distributed, with little attention given to the unique characteristics of educational settings, where students are nested within schools and there are hierarchical dependencies. The goal of this study is to propose a framework for designing OTRs from multisite randomized trials, a commonly used experimental design in education and psychology to evaluate educational programs. We investigate modifications to popular OTR methods, specifically Q-learning and weighting methods, in order to improve their performance in multisite randomized trials. A total of 12 modifications, 6 for Q-learning and 6 for weighting, are proposed by utilizing different multilevel models, moderators, and augmentations. Simulation studies reveal that all Q-learning modifications improve performance in multisite randomized trials and the modifications that incorporate random treatment effects show the most promise in handling cluster-level moderators. Among weighting methods, the modification that incorporates cluster dummies into moderator variables and augmentation terms performs best across simulation conditions. The proposed modifications are demonstrated through an application to estimate an OTR of conditional cash transfer programs using a multisite randomized trial in Colombia to maximize educational attainment.

最佳治疗方案(OTR)已被广泛应用于计算机科学和个性化医学,为个人提供数据驱动的最佳建议。然而,以前对OTR的研究主要集中在独立和相同分布的环境上,很少关注教育环境的独特特征,即学生嵌套在学校中,存在等级依赖性。本研究的目的是从多站点随机试验中提出一个设计OTR的框架,这是教育和心理学中常用的评估教育项目的实验设计。我们研究了对流行的OTR方法的修改,特别是Q学习和加权方法,以提高它们在多站点随机试验中的性能。通过利用不同的多级模型、调节因子和增广,总共提出了12种修改,其中6种用于Q学习,6种用于加权。模拟研究表明,在多站点随机试验中,所有Q学习修改都能提高性能,而结合随机治疗效果的修改在处理集群级调节因子方面最有希望。在加权方法中,将聚类假人纳入调节变量和增强项的修改在模拟条件下表现最好。通过在哥伦比亚进行的多站点随机试验来估计有条件现金转移项目的OTR,以最大限度地提高教育程度,从而证明了拟议的修改。
