Conduct a Forward: LRlogistic regression analysis with the following variables
IV -age, edu, hrsl, sibs, rincom91, life2 (categorical)
DV -satjob2
Note: The variable life2 is categorical such that dull = 1, routine/exciting =2, and all other values are system missing.
1. Develop a research question for the preceding scenario;
2.Conduct apreliminary Linear Regressionto identify outliers and evaluate multicollinearity among the five continuous variables.
Complete the following:
- Using the Chi-Square table in Appendix B near the end of this book, identify the critical value at p < .001 for identifying outliers.
- Use Explore to determine if there are outliers. Which cases should be eliminated?
- Is multicollinearity a problem among the five continuous variables?
- ConductBinary Logistic Regression using the Forward: LR method.
IV - age, edu, hrsl, sibs, rincom91, life2 (categorical: last is the reference category)
DV - satjob2
Note: Make sure that any outliers identified in Exercise 2. a. are removed from data before running the logistic regression. Also, designating life2 as a categorical covariate with the last category as the reference, essentially makes routine/exciting = 0 and dull = 1, so interpret the results accordingly.
- Which variables were entered into the model?
- To what degree does the model fit the data? Explain
- Is the generated model significantly different from the constant-only model?
- How accurate is the model in predicting job satisfaction?
- What are the odds ratios for the model variables? Explain.
