Below are the output from a binary logistic regression analysis where the dependent Variable Survived coded as 1 for Survived and 0 for Not Survived and independent Variables: Age, Fare, Sex. c) Review Part B output and interpret odds ratios for the variables. d) Review Part C output and comment on the classification accuracy of the model.
Dependent Variable: Survived 1- Survived and 0 - Not Survived |
Independent Variables: Age, Fare, Sex |
Part A:
Chi-sq: 13.55; df: 3; p-value: 0.003 and alpha: 0.05
Part B:
coeff b | s.e. | Wald | p-value | exp(b) | lower | upper | |
Intercept | -2.71 | 1.4 | 3.76 | 0.05 | 0.07 | ||
Age | 0.05 | 0.04 | 1.64 | 0.2 | 1.05 | 0.97 | 1.14 |
Fare | 0 | 0.02 | 0.09 | 0.77 | 1 | 0.96 | 1.03 |
Sex | 2.95 | 1.01 | 8.58 | 0.00 | 19.19 | 2.66 | 138.52 |
Lower and upper columns are 95% confidence limits for the odds ratios exp(b).
Part C:
Suc-Obs | Fail-Obs | Total | |
Suc-Pred | 12 | 3 | 15 |
Fail-Pred | 3 | 12 | 15 |
Total | 15 | 15 | 30 |
