Yapısal Eşitlik Modellemesi-Structural Equation Model
Structural equation modelling is a multivariate statistical method, with the integration of factor analysis and multi-regression analysis so as to simultaneously estimate dependence relationships. Structural equation modelling is used in various disciplines to solve research problems concerning casual relationships between implicit structures measured by the observed variables.

Structural Equation Modeling on the Internet
Congruent with its purpose, the Structural Equation Modeling SIG of AERA maintains an index of SEM-related resources available on the WWW. If you are maintaining a WWW site related to structural equation modeling, please send the URL to Greg Hancock, Chair, AERA SIG: Structural Equation Modeling, to be considered for inclusion in this listing.

Karl G. Jöreskog: New Research Paper
C. Van Tuyckom, & K. Jöreskog, “Going for gold! Welfare characteristics and Olympic success: an application of the structural equation approach.” Quality & Quantity (in press)
Winning
medals at the Olympic Games has become an objective that countries
worldwide want to achieve. In line with research
devoted to the predictors of success, the present article
examines the connection between certain welfare characteristics
(political, social, and economic development) and the
probability of success in the 1984 and 2004 Olympics. We expected to
find that structural macro conditions still predict Olympic
success. Using welfare indicators as formative instead of reflective
indicators (Bollen, Qual Quant 183: 77–85, 1984, p. 65), the
results of our Structural Equation Model reveal that both economic
and social development had an effect in 1984, as well as in
2004. Political development was only significant in 1984. As for
the control variables, population size was significant in
both 1984 and 2004. Sporting tradition and geographical conditions
had no effect at all. The model fit is very good with a
chi-square of 6.62 with 5 degrees of freedom (p = 0.25).
lavaan - latent variable analysis
What is lavaan?
lavaan is a free, open source R package for latent variable analysis. You can use lavaan to estimate a large variety of multivariate statistical models, including path analysis, confirmatory factor analysis, structural equation modeling and growth curve models.The lavaan package is developed to provide useRs, researchers and teachers a free open-source, but commercial-quality package for latent variable modeling. The long-term goal of lavaan is to implement all the state-of-the-art capabilities that are currently available in commercial packages.
