?The Kleinbaum Sample ProblemThis problem comes from an example in the text: David G. Kleinbaum. Logistic Regression: A Self-Learning Text. New York: Springer-Verlag, 1966. Pages 256-257.The problem is to examine the relationship between the dependent variable Confidence in the legal system, (CONFIDEN) and three independent variables: Social class (CLASS), Number of times victimized (VICTIM), and age (AGE).Confidence in the legal system, the dependent variable, is metric so we could use multiple regression analysis. However, the author opts to convert Confidence in the legal system to a dichotomous variable by dividing the score above and below the median value of 10. A new dependent variable, High confidence in the legal system (HIGHCONF) was created where 1 stands for high confidence and 0 stands for low confidence.The data for this problem is: ConfidenceInLegalSystem.Sav.Kleinbaum Logistic Regression Problem1 Stage One: Define the Research ProblemIn this stage, the following issues are addressed:Relationship to be analyzedSpecifying the dependent and independent variablesMethod for including independent variablesKleinbaum Logistic Regression ProblemRelationship to be analyzedThe problem is to examine the relationship between the dependent variable Confidence in the legal system, (CONFIDEN) and three independent variables: Social class (CLASS), Number of times victimized (VICTIM), and age (AGE).2 Specifying the dependent and independent variablesThe dependent variable, High confidence in the legal system (HIGHCONF) was created so that 1 stands for high confidence and 0 stands for low confidence.The independent variables are:CLASS? Social class statusVICTIM? Number of times victimizedAGE? Age of respondentCLASS? Social class status is a nonmetric variable with three response options: 1 = Low, 2 = Medium, and 3 = High.? While a case could be made that it can be treated as a scale variable, we will treat it as nonmetric and use the SPSS facility in logistic regressio
