PPT-Structural equation models and confirmatory factor analysis in small samples: theory and

Andrej Srakar PhD Institute for Economic Research Ljubljana and Faculty of Economics University of Ljubljana Slovenia 1 Structure of the presentation Research. Overview Our theories often lead us to be interested in how a series of variables are interrelated It is therefore often desirable to develop a system of equations ie a model which specifies all the causal linkages between variablesFor example statu and Structural Equations Models.
