The present article features a hierarchical Bayes method applied to solving problems of benchmarking and contemporaneous reconciliation across time series. This method enables the use of high frequency series to be either approximations or one or several related indicators. This method may be applied when facing flow or index disaggregation problems. The authors compare their results to classical procedures (viz., Denton univariate and Rossi multivariate methods) through the use of indicators. This article concludes that the suggested method bestows greater importance on the low frequency series profile, consequently providing smoother solutions than its counterparts.
本文采用层次贝叶斯方法来解决跨时间序列的基准和同期和解问题。这种方法使高频序列的使用既可以是近似值,也可以是一个或几个相关指标。这种方法可以应用于流或索引分解问题。作者通过使用指标将他们的结果与经典程序(即丹顿单变量和罗西多变量方法)进行比较。本文的结论是,所建议的方法给予低频系列轮廓更大的重要性,因此提供更平滑的解决方案比其同行。

The present study considered two independent exponential distributions with the hypothesis for testing equivalence of lifetime means or failure rates, and aimed to determine the required uncensored sample size based on power, sampling cost, and censoring proportion simultaneously in the case of right censoring. Approximate sample size formulas with an iterative procedure were proposed and an uncensored sample size allocation ratio was derived to minimize the total cost for a designated power or maximize statistical power for a limit cost. R codes are provided for easy application. The proposed methods are validated in terms of Type I errors and statistical power in a simulation study, and are recommended for the future use.
本研究考虑两个独立的指数分布,以检验寿命均值或故障率的等效性为假设,旨在同时确定在正确审查的情况下,基于功率、抽样成本和审查比例所需的未审查样本量。提出了近似的样本量计算公式,并推导出了一个不受审查的样本量分配比例,以使指定功率的总成本最小化,或使统计功率的极限成本最大化。R代码提供了方便的应用。在模拟研究中,根据I型误差和统计功率验证了所提出的方法,并建议将来使用。

The form-resistant hypothesis states that alternative ways of measuring the same values should be small if method-specific features are taken into account. However, previous research that compared rating and ranking questionnaires for measuring values has shown mixed results. We suggest that adopting a latent class segmentation approach helps to explain these mixed results by identifying segments with similar item preference structures and segments linked to one format only. Our approach is applied to a Dutch survey on work values. In both ranking and rating mode, we find two similar segments reflecting the intrinsic and extrinsic preference structure, while other segments differed between modes. In line with the modified form-resistant hypothesis, the results suggest the same latent preference structure has guided particular segments in a population to respond similarly to rating and ranking questions.
抗形式假设指出,如果考虑到方法特定的特征,测量相同值的替代方法应该很小。然而,之前的研究比较了评级和排名问卷来衡量价值,结果喜忧参半。我们建议采用潜在类分割方法,通过识别具有相似项目偏好结构的片段和仅链接到一种格式的片段,有助于解释这些混合结果。我们的方法应用于荷兰的一项关于工作价值的调查。在排名和评级模式中,我们发现两个相似的片段反映了内在和外在偏好结构,而其他片段则在不同的模式中有所不同。与修正的形式抵抗假说一致,结果表明,相同的潜在偏好结构引导了人群中的特定部分对评级和排名问题做出类似的反应。

Investigation of Parameter Estimation Accuracy for Growth Curve Modeling With Categorical Indicators: Impact of Number of Measurement Occasions and Number of Categories 分类指标生长曲线建模参数估计精度研究:测量次数和类别数的影响

Growth curve modeling (GCM) is an important and commonly used methodology in the social sciences for examining change over time in a variable value. While much of the empirical research examining the performance of various estimators under a variety of conditions has focused on continuous (and typically normally distributed) observed indicators, in practice researchers frequently make use of categorical indicators with anywhere from two to as many as seven categories. Given the popularity of GCMs, along with the frequent use of categorical indicators, and the relative dearth of simulation research focusing on estimation of these models with such variables, the current study focused on the issue of parameter estimation accuracy as related to the number of categorical indicators, and the number of categories per indicator. Results of this research found that for models with only a linear component, parameter estimation was very accurate for as few as four indicators with two categories each and a sample size of 200. On the other hand, when the underlying model included both linear and quadratic terms, parameter estimation accuracy suffered for a small number of dichotomous indicators unless the sample size was 1,000 or more. However, with six or more indicator variables, and/or at least three categories, parameter estimation accuracy remained high.
增长曲线模型(GCM)是社会科学中一种重要且常用的方法,用于检查变量值随时间的变化。虽然检验各种估计器在各种条件下的性能的许多实证研究都集中在连续(通常是正态分布的)观察指标上,但在实践中,研究人员经常使用从2到多达7个类别的分类指标。鉴于gcm的普及,以及分类指标的频繁使用,以及关注这些变量对这些模型进行估计的模拟研究相对缺乏,目前的研究重点是与分类指标数量和每个指标的类别数量相关的参数估计精度问题。本研究结果发现,对于只有线性成分的模型,参数估计非常准确,只有4个指标,每两个类别,样本量为200。另一方面,当底层模型同时包含线性项和二次项时,除非样本量为1,000或更多,否则少数二分类指标的参数估计精度会受到影响。然而,有六个或更多的指标变量,和/或至少三个类别,参数估计精度仍然很高。

In repeated cross-sections of organizations, different individuals are sampled from the same set of organizations at each time point of measurement. As a result, common longitudinal data analysis methods (e.g., latent growth curve models) cannot be applied in the usual way. In this contribution, a multilevel structural equation modeling approach to analyze data from repeated cross-sections is presented. Results from a simulation study are reported which aimed at obtaining guidelines on appropriate sample sizes. We focused on a situation where linear growth occurs at the organizational level, and organizational growth is predicted by a single organizational level variable. The power to identify an effect of this organizational level variable was moderately to strongly positively related to number of measurement occasions, number of groups, group size, intraclass correlation, effect size, and growth curve reliability. The Type I error rate was close to the nominal alpha level under all conditions.
在组织的重复横截面中,在每个测量时间点从同一组组织中抽取不同的个体。因此,常用的纵向数据分析方法(如潜在增长曲线模型)无法正常应用。在这篇贡献中,提出了一种多层结构方程建模方法来分析来自重复截面的数据。报告了一项模拟研究的结果,该研究旨在获得适当样本量的指导方针。我们关注的是线性增长发生在组织层面的情况,并且组织增长是由单个组织层面变量预测的。识别该组织水平变量影响的能力与测量次数、组数、组大小、类内相关性、效应大小和生长曲线可靠性呈正相关。在所有条件下,I型错误率接近名义α水平。

Abstract. Theoretical researchers consider Structural Equation Modeling (SEM) to be the preferred method to study the relationships among latent variables. However, SEM has the disadvantage of requiring a large sample size, especially if the model is complex. Furthermore, since SEM estimates all parameters simultaneously, one misspecification in the model may influence the whole model. For these reasons, applied researchers often use a two-step Factor Score Regression (FSR) approach. In the first step, factor scores are calculated for the latent variables, which are used to perform a linear regression in the second step. However, this method results in incorrect regression coefficients. Croon (2002) developed a method that corrects for this bias. We combine this method of Croon (2002) with path analysis, resulting in Factor Score Path Analysis.

摘要理论研究人员认为,结构方程建模(SEM)是研究潜在变量之间关系的首选方法。然而,SEM的缺点是需要大的样本量,尤其是在模型复杂的情况下。此外,由于SEM同时估计所有参数,因此模型中的一个错误指定可能会影响整个模型。由于这些原因,应用研究人员通常使用两步因素得分回归(FSR)方法。在第一步中,计算潜在变量的因子得分,这些因子得分用于在第二步中执行线性回归。然而,这种方法会导致不正确的回归系数。Croon(2002)开发了一种方法来纠正这种偏差。我们将Croon(2002)的这种方法与路径分析相结合,得出了因子得分路径分析。该方法得到了正确的路径系数,并且与SEM相比具有一些优点:它需要更小的样本量,可以处理更复杂的模型,并且该方法。。。

Abstract. Researchers use latent class (LC) analysis to derive meaningful clusters from sets of categorical variables. However, especially when the number of classes required to obtain a good fit is large, interpretation of the latent classes may not be straightforward. To overcome this problem, we propose an alternative way of performing LC analysis, Latent Class Tree (LCT) modeling. For this purpose, a recursive partitioning procedure similar to divisive hierarchical cluster analysis is used: classes are split until a certain criterion indicates that the fit does not improve. The advantage of the LCT approach compared to the standard LC approach is that it gives a clear insight into how the latent classes are formed and how solutions with different numbers of classes relate. We also propose measures to evaluate the relative importance of the splits. The practical use of the approach is illustrated by the analysis of a data set on social capital.
摘要研究人员使用潜在类(LC)分析从分类变量集合中得出有意义的聚类。然而,特别是当获得良好拟合所需的类的数量很大时,对潜在类的解释可能并不简单。为了克服这个问题,我们提出了一种执行LC分析的替代方法,即潜在类树(LCT)建模。为此,使用了类似于分裂层次聚类分析的递归划分过程:类被分割,直到某个标准表明拟合没有改善。与标准LC方法相比,LCT方法的优势在于,它可以清楚地了解潜在类是如何形成的,以及具有不同类数的解决方案是如何关联的。我们还提出了评估分裂相对重要性的措施。通过对社会资本数据集的分析说明了该方法的实际应用。

Residual correlations and covariances provide effect sizes of the misfit of covariance structure models. In a simulation study, we found that accurate confidence intervals (CIs) for standardized residual covariances are obtained even in small samples (N = 100), regardless of model size, degree of model misspecification, and data distribution. Standardized residual covariances also provide information about the source of misfit in poorly fitting models. From this viewpoint, they may be considered an alternative to modification indices. We compared the empirical Type I errors and power rates of standardized residual covariances and modification indices and found that both procedures provide nearly identical rates across the simulation conditions investigated. Residual correlations and standardized residual covariances provide very similar results.
残差相关和协方差提供了协方差结构模型失配的效应大小。在一项模拟研究中,我们发现即使在小样本(N = 100)中,无论模型大小、模型错配程度和数据分布如何,标准化残差协方差的准确置信区间(ci)也能得到。标准化的残差协方差也提供了在拟合不良的模型中失配的来源的信息。从这个角度来看,它们可以被视为修改索引的替代方案。我们比较了标准化残差协方差和修正指数的经验I型误差和功率率,发现这两种方法在所调查的模拟条件下提供了几乎相同的率。残差相关和标准化残差协方差提供了非常相似的结果。

A general procedure for testing inequality constrained hypotheses in SEM 扫描电镜中检验不等式约束假设的一般程序

Abstract. Researchers in the social and behavioral sciences often have clear expectations about the order and/or the sign of the parameters in their statistical model. For example, a researcher might expect that regression coefficient β1 is larger than regression coefficients β2 and β3. To test such a constrained hypothesis special methods have been developed. However, the existing methods for structural equation models (SEM) are complex, computationally demanding, and a software routine is lacking. Therefore, in this paper we describe a general procedure for testing order/inequality constrained hypotheses in SEM using the R package lavaan. We use the likelihood ratio (LR) statistic to test constrained hypotheses and the resulting plug-in p value is computed by either parametric or Bollen-Stine bootstrapping. Since the obtained plug-in p value can be biased, a double bootstrap approach is available. The procedure is illustrated by a real-life example about the psychosocial functioning in patients with fac...
摘要社会科学和行为科学的研究人员通常对其统计模型中参数的顺序和/或符号有明确的期望。例如,研究人员可能期望回归系数β1大于回归系数β2和β3。为了检验这样一个受约束的假设,人们开发了一些特殊的方法。然而,现有的结构方程模型(SEM)方法复杂,计算量大,且缺乏软件程序。因此,在本文中,我们描述了使用R包lavaan测试SEM中阶/不等式约束假设的一般过程。我们使用似然比(LR)统计量来检验约束假设,并通过参数或Bollen-Stine bootstrapping计算得到的插件p值。由于获得的插件p值可能存在偏差,因此可以使用双自举方法。这一过程是通过一个现实生活中的例子来说明的,这个例子是关于面瘫患者的心理社会功能。

Therefore, in this paper we describe a general procedure for testing order/inequality constrained hypotheses in SEM using the R package lavaan. We use the likelihood ratio (LR) statistic to test constrained hypotheses and the resulting plug-in p value is computed by either parametric or Bollen-Stine bootstrapping. Since the obtained plug-in p value can be biased, a double bootstrap approach is available. The procedure is illustrated by a real-life example about the psychosocial functioning in patients with fac...","PeriodicalId":18476,"journal":{"name":"Methodology: European Journal of Research Methods for The Behavioral and Social Sciences","volume":"13 1","pages":"61-70"},"PeriodicalIF":3.1,"publicationDate":"2017-06-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"44064733","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"心理学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Culpepper and Aguinis (2011) highlighted the benefit of using the errors-in-variables (EIV) method to control for measurement error and obtain unbiased regression estimates. The current study investigated the EIV method and compared it to change scores and analysis of covariance (ANCOVA) in a two-group pretest-posttest design. Results indicated that the EIV method’s estimates were unbiased under many conditions, but the EIV method consistently demonstrated lower power than the change score method. An additional risk with using the EIV method is that one must enter the covariate reliability into the EIV model, and results highlighted that estimates are biased if a researcher chooses a value that differs from the true covariate reliability. Obtaining unbiased results also depended on sample size. Our conclusion is that there is no additional benefit to using the EIV method over change score or ANCOVA methods for comparing the amount of change in pretest-posttest designs.
Culpepper和Aguinis(2011)强调了使用变量误差(EIV)方法控制测量误差和获得无偏回归估计的好处。本研究对EIV方法进行了研究,并将其与两组前测后测设计中的变化评分和协方差分析(ANCOVA)进行了比较。结果表明,EIV方法的估计在许多条件下是无偏的,但EIV方法始终显示出低于变化评分方法的功率。使用EIV方法的另一个风险是必须将协变量可靠性输入EIV模型,并且结果强调,如果研究人员选择的值与真正的协变量可靠性不同,则估计是有偏差的。获得无偏结果也取决于样本量。我们的结论是,在比较前测-后测设计的变化量时,使用EIV方法与变化评分或ANCOVA方法相比没有额外的好处。
