Journal ArticleDOI
OpenMx: An Open Source Extended Structural Equation Modeling Framework
Steven M. Boker,Michael C. Neale,Hermine H. Maes,Michael Wilde,Michael Spiegel,Timothy R. Brick,Jeffrey R. Spies,Ryne Estabrook,Sarah Kenny,Timothy C. Bates,Paras D. Mehta,John Fox +11 more
TL;DR: The OpenMx data structures are introduced—these novel structures define the user interface framework and provide new opportunities for model specification and a discussion of directions for future development.
Journal ArticleDOI
OpenMx 2.0: Extended Structural Equation and Statistical Modeling
Michael C. Neale,Michael D. Hunter,Joshua N. Pritikin,Mahsa Zahery,Timothy R. Brick,Robert M. Kirkpatrick,Ryne Estabrook,Timothy C. Bates,Hermine H. Maes,Steven M. Boker +9 more
TL;DR: Ease-of-use improvements include helper functions to standardize model parameters and compute their Jacobian-based standard errors, access to model components through standard R $ mechanisms, and improved tab completion from within the R Graphical User Interface.
Journal ArticleDOI
Life Satisfaction Shows Terminal Decline in Old Age: Longitudinal Evidence from the German Socio-Economic Panel Study (SOEP).
Denis Gerstorf,Nilam Ram,Ryne Estabrook,Jürgen Schupp,Jürgen Schupp,Gert G. Wagner,Gert G. Wagner,Ulman Lindenberger +7 more
TL;DR: The evidence suggests that late-life changes in aspects of well-being are driven by mortality-related mechanisms and characterized by terminal decline.
Journal ArticleDOI
Identification of Confirmatory Factor Analysis Models of Different Levels of Invariance for Ordered Categorical Outcomes
Hao Wu,Ryne Estabrook +1 more
TL;DR: By analyzing the transformation that leaves the model-implied probabilities of response patterns unchanged, this article gives identification conditions for models with invariance of different types of parameters without referring to a specific parametrization of the baseline model.
Journal ArticleDOI
Clinical Implications of a Dimensional Approach: The Normal:Abnormal Spectrum of Early Irritability.
Lauren S. Wakschlag,Ryne Estabrook,Amélie Petitclerc,David Henry,James L. Burns,Susan B. Perlman,Joel L. Voss,Daniel S. Pine,Ellen Leibenluft,Margaret L. Briggs-Gowan +9 more
TL;DR: In this article, the authors examined longitudinal, dimensional patterns of irritability and their clinical import in early childhood and found that even mildly elevated Temper Loss scale scores showed substantially increased risk of symptoms and disorders.
