Model Search With Tetrad II and Lisrel
This article is a comment on the paper by Spirtes, Scheines, and Glymour. The problem of equivalent models is discussed. The conclusion of the authors that the automatic model modification procedure in LISREL performs poorly may be due to the fact that all equivalent models are not counted as correct models. Our own experiment based on their model 8 demonstrates that the automatic model modification procedure in LISREL indeed performs very well w…
Model Modification
An analysis of empirical data often leads to a rejection of a hypothesized model, even if the researcher has spent considerable efforts in including all available information in the formulation of the model. Thus, the researcher must reformulate the model in some way, but in most instances there is, at least theoretically, an overwhelming number of possible actions that could be taken. In this paper a “modification index” will be discussed which …
The stress chain
A conceptual core model of the teacher stress process, assumed to be invariant, was tested on longitudinal data. A LISREL analysis confirmed the goodness of fit of the model. Teachers' relations to pupils and teachers' perception of pupils as a stress source result in general strain, and in turn lead to various stress reactions. Teachers who perceive students as stressors at the middle of the first term report general strain and impaired somatic …
Recent Developments in Structural Equation Modeling
The authors describe new developments in structural equation modeling as incorporated in LISREL V. The procedures are illustrated on data from three previous studies.
A General Method for Studying Differences in Factor Means and Factor Structure Between Groups
A statistical model is developed for the study of similarities and differences in factor structure between several groups. The model assumes that the observed variables satisfy a factor analysis model in each group. A method of data analysis is presented which, in contrast to earlier work, makes use of information in the observed means as well as the observed variances and covariances to estimate the parameters in each group, i.e. factor means, f…
