Estimate a multiple regression model with Work as the dependent variable and Custort Comport and Intcord as predictors

INSTRUCTIONS TO CANDIDATES

ANSWER ALL QUESTIONS

1. Estimate a three-factor confirmatory factor analysis model with ‘Role Amb’, ‘Role Conf’ and ‘Cust Foc’ as latent variables.

2. Estimate a model with ‘Mkt Ort’ as a determinant/predictor of ‘Job Sat’ and ‘Cust Foc’.

3. For the model estimated in 2. above, test the hypothesis that ‘Mkt Ort’ has the same influence on ‘Job Sat’ and ‘Cust Foc’ against the alternative hypothesis that its influence is different.

4. Test the hypothesis that ‘Mkt Ort’ has the same influence on all its indicators against the alternative hypothesis that ‘Mkt Ort’ has the same influence on all its indicators AND the measurement errors of the latter are the same.

5. Estimate a multiple regression model with Work as the dependent variable and Custort, Comport and Intcord as predictors.

6. Add Pay as a dependent variable to the model estimated in 5. above and test the hypothesis that Custort, Comport and Intcord all have the same influence on Pay against the alternative hypothesis that their influence is different.

7. Estimate the following “chain” model: ‘Mkt Ort’ -> ’Role Amb’-> ’Role Conf’- > ‘Job Sat’

8. How many (and which) constraints, are included in the structural part of the chain model in 7 above?

9. Compare the fit of the model in 7. above with the fit of a model where ‘Mkt Ort’, ‘Role Amb’, ‘Role Conf’ are all exogenous latent variables impacting a single endogenous latent variable, namely ‘Job Sat’.

10. Re-estimate the model under 7. above but assume that the sample size is 3000 instead of 306. Comment on the differences in the results.
