Klasik Test Kuramı ve Madde Tepki Kuramına Göre Kestirilen Parametrelerle Sınırlandırılan Yapısal Eşitlik Modellerinin Uyum İndekslerinin Karşılaştırılması

Abstract

Even though confirmatory factor analysis and structural equation modeling consists of way analysis are frequently used by researchers, prior to analysis it is seen that examination of assumptions, appropriate parameter estimation method for selecting the operations are not performed or reported. In situation of model assumptions of not meeting or number of parameters estimated is less than data in variance-covariance matrix, parameters are restricted. Determination of items in accordance with the structure of the models, as a consequence of different scenarios based on limited parameters (1, CTT and IRT values), a comparison is aimed between estimation methods for different parameters of models and estimated goodness of fit index.
