4. (Optional). Assume that you have downloaded Dream_Holiday.sav: recall that the eighty-eight statements belong to six topics. Would the interpretation be helped if one carried out, say, a factor analysis on each subtopic?
3. (Optional) Go to the website connected to this book, www.pearsoned.co.uk/schmidt.Download the SPSS file Dream_Holiday.sav. Try to run the analysis using the above settings but with a different number of factors, say, with eight factors. How do you find this solution compared with your

■ Show how to run a factor analysis in SPSS.
■ Outline how factor analysis can be used as input for an advertising strategy.
■ Understand why a rotation of factors often facilitates an interpretation.
■ Explain principles for deciding on the number of factors to extract.
■ Differentiate between a factor and a variable.
■ Describe the purpose of conducting a factor analysis.
■ Explain similarities between factor analysis and cluster analysis.
3. Finally, compare all four outputs obtained (two discriminant and two logistic regressions) with the original regression analysis output (Table 9.12). Which comparisons can be made between the regression output and the output from the discriminant analysis and from logistic regression?
2. Using the same data, now run two binary logistic regressions. Compare the two logistic regression models with regard to overall model fit and coefficient significance.Which run would you regard most successful and why?
1. The table below once more displays the small numerical example data set used for regression analysis (Table 9.14). In the same table we have twice been recoding values of the dependent variable Y1. In column IIa, values of Y1/II have been recoded so that 3, 4, and 5 are transformed to 1 while 1
■ Show how a logistic regression must be interpreted – compared with an ordinary regression analysis.
■ Clarify when a logistic regression analysis is appropriate and explain the difference between discriminant analysis and logit models.
