Items that are clustered according to shared content may violate the principle of conditional independence commonly used in item response theory. This paper investigates the capabilities of a logistic item response model in relation to loca...
Evaluation of latent construct correlations in the presence of missing data: a note on a latent variable modelling approach [0.03%]

A latent variable modelling approach is discussed, which can be used to evaluate indices of linear relationship between latent constructs in incomplete data sets. The method is based on an application of maximum-likelihood estimation and in...

We study the effect of excess kurtosis on the non-centrality parameters of the rescaled and the residual-based test statistics for covariance structure models. The analysis is based on population matrices and parameters, which eliminates th...

Multiple item response profile (MIRP) models are models with crossed fixed and random effects. At least one between-person factor is crossed with at least one within-person factor, and the persons nested within the levels of the between-per...

Longitudinal data analysis focused on internal characteristics of a single time series has attracted increasing interest among psychologists. The systemic psychological perspective suggests, however, that many long-term phenomena are mutual...
Traditional and proposed tests of slope homogeneity for non-normal and heteroscedastic data [0.03%]

The purpose of this study was to develop and compare tests of independent groups' slopes for non-normal distributions and heteroscedastic variances, including slope tests based on least squares, Theil-Sen, and trimmed estimation approaches....

The statistical power of a hypothesis test is closely related to the precision of the accompanying confidence interval. In the case of a z-test, the width of the confidence interval is a function of statistical power for the planned study. ...
A latent trait model for response times on tests employing the proportional hazards model [0.03%]
比例优势假设下的反应时潜变量模型研究

Jochen Ranger
For computer-administered tests, response times can be recorded conjointly with the corresponding responses. This broadens the scope of potential modelling approaches because response times can be analysed in addition to analysing the respo...
