Objectives Upon completing this chapter, the learner should be able to:
- State or recognize the difference between nominal and
ordinal variables. - State or recognize when the use of polytomous logistic
regression may be appropriate. - State or recognize the polytomous regression model.
- Given a printout of the results of a polytomous logistic
regression:
a. State the formula and compute the odds ratio
b. State the formula and compute a confidence
interval for the odds ratio
c. Test hypotheses about the model parameters using
the likelihood ratio test or the Wald test, stating the
null hypothesis and the distribution of the test
statistic with the corresponding degrees of freedom
under the null hypothesis - Recognize how running a polytomous logistic
regression differs from running multiple standard
logistic regressions.
