Examining the Performance of the Modified ADF Goodness-of-fit Test Statistic in Structural Equation Models
Foldnes, Njål; Marcoulides, George A.; Olsson, Ulf H. (Journal article; Peer reviewed, 2019)The asymptotically distribution-free (ADF) test statistic depends on very mild distributional assumptions and is theoretically superior to many other so-called robust tests available in structural equation modeling. The ... -
A faster procedure for estimating CFA models applying Minimum Distance Estimators
Kreiberg, David; Marcoulides, Katerina; Olsson, Ulf H. (Journal article; Peer reviewed, 2020)This paper presents a numerically more efficient implementation of the quadratic form minimum distance (MD) estimator with a fixed weight matrix for confirmatory factor analysis (CFA) models. In structural equation modeling ... -
The choice of normal-theory weight matrix when computing robust standard errors in confirmatory factor analysis
Foldnes, Njål; Olsson, Ulf H. (Journal article; Peer reviewed, 2019)Robust standard errors are of central importance in confirmatory factor models. In calculating these statistics a central ingredient is the inverse of the asymptotic covariance matrix of second-order moments calculated ...
