Ranking metrics in network meta-analysis (NMA) are computed separately for each outcome. Our aim is to 1) present graphical ways to group competing interventions considering multiple outcomes and 2) use conjoint analysis for placing weights on the va

Rotation to sparse loadings using Lp losses and related inference problems

Autor: Xinyi Liu, Gabriel Wallin, Yunxiao Chen, Irini Moustaki

Researchers have widely used exploratory factor analysis (EFA) to learn the latent structure underlying multivariate data. Rotation and regularised estimation are two classes of methods in EFA that they often use to find interpretable loading matrice

Assessing Partial Association Between Ordinal Variables: Quantification, Visualization, and Hypothesis Testing

Autor: Shaobo Li, Irini Moustaki, Dungang Liu, Yan Yu

Publikováno v: Journal of the American Statistical Association. 116:955-968

Partial association refers to the relationship between variables Y1,Y2,…,YK while adjusting for a set of covariates X={X1,…,Xp}. To assess such an association when Yk’s are recorded on ordinal scales, a classical approach is to use partial corr

The asymptotic power of the Lagrange multiplier tests for misspecified IRT models

Autor: Silvia Cagnone, Lucia Guastadisegni, Vassilis G. S. Vasdekis, Irini Moustaki

Publikováno v: Springer Proceedings in Mathematics & Statistics ISBN: 9783030747718

This article studies the power of the Lagrange Multiplier Test and the Generalized Lagrange Multiplier Test to detect measurement non-invariance in Item Response Theory (IRT) models for binary data. We study the performance of these two tests under c
