Estimation method choice in the factor scale creation

Summary/Abstract: Some estimation models in the structural equation modelling as well as their characteristics are discussed in this article. An attempt of the scale construction to measure securing in households' old age with the use of structural equation modelling is presented too. Characteristics of each method decided on the estimation choice. Simulation survey results concerning robustness degree of each method on the deviation from the normal distribution, sample size, defective model specification etc. were taken into account too. Two measuring models were discussed: taking one common factor and three common factors. The factor confirmative analysis was conducted to verify the proposed models. Estimations made by the maximum likelihood (ML) method and by generalized least square estimator were compared, which shall give symptomatic correlated results assuming that the model specification is correct.
