Factor Analysis and Structural Equation Modeling The data for part b) and c) are to be found at my homepage: http://www.bi.no/users/fgl96027/ a) Figure 1 shows a structural model. Substitute standard notation for the letters A through G and a through w. Use the standard notation to represent the model in equation form. Classify the parameters as belonging to either the measurement part or the structural part of the model. m x1 a l k A n E x2 b o C D w G c x3 F s t u v B p q y1 y2 g h y3 y4 i j r x4 x5 x6 d e f Figure 1 b) Use the dataset in the PSF-file: Case-Gra6020S-2004.psf i) Start with a data screening (N=533) ii) Do an exploratory factor analysis and try to find a suitable factor structure iii) Based on ii), estimate and test the CFA-model. It could be a good idea to try several estimators. Comment on your findings. c) In a study to determine the predictors of drinking and driving behavior among 18to 24-years-old males, the following model was proposed (N=356): 1 111 12 2 13 3 1 2 211 2 1 : Intentions to drink and drive ( y1 and y2 ) 2 : Drinking and driving behavior ( y3 and y 4 ) 1 : Attitude toward drinking and driving ( x1 x3 ) 2 : Social norms pertaining to drinking and driving ( x4 x6 ) 3 : Perceived control over drinking and driving ( x7 and x8 ) Use the covariance matrix to estimate the parameters of the structural model. Comment on the model fit. The covariance matrix is to be found in the file: Drinkd.cov. Here you will find a matrix of 12 variables listed in the following order y1 y 4 , x1 x8 . I.e., there are four y-variables and eight x-variables, and the y-variables are listed first in the covariance matrix.
