Logistic Analysis
Examine Relationships between a Categorical Y and a Continuous X Variable
The Logistic platform fits the probabilities for response categories to a continuous x predictor. The fitted model estimates probabilities for each x value. The Logistic platform is the nominal or ordinal by continuous personality of the Fit Y by X platform. There is a distinction between nominal and ordinal responses on this platform:
•
Nominal logistic regression estimates a set of curves to partition the probability among the responses.
•
Ordinal logistic regression models the probability of being less than or equal to a given response. This has the effect of estimating a single logistic curve, which is shifted horizontally to produce probabilities for the ordered categories. This model is less complex and is recommended for ordered responses.
