How to Run Ordered Logit Regression

The Ordered Logit is a form of regression analysis that models a discrete and ordinal dependent variable with more than two outcomes (Net promoter Score, Customer Satisfaction rating, etc.).

This article describes how to create an Ordered Logit Regression output as shown below. The example below is a model that predicts an overall satisfaction score based on satisfaction with specific features.

Requirements

Familiarity with the Structure and Value Attributes of Variable Sets, and how they are used in regression models per our Driver Analysis ebook.
An Ordinal Outcome variable with at least three outcomes to be predicted. Ideally, an Ordinal variable. When using stacked data, the Outcome variable should be a single question in a Multi-type structure (eg, Ordinal-Multi).
Continuous, categorical, or binary predictor variables will be considered as predictors of the outcome variable. When using stacked data, the Predictor(s) must be a single question in a Grid type structure (Binary - Grid).

Method

From the Report tree select + > Advanced Analysis > Regression > Ordered Logit.
In the Object Inspector Go to the Data tab.
In the Output menu, select the binary variable to be predicted by the predictor variables.
Select the predictor variable(s) from the Predictor(s) list.
OPTIONAL: Select the desired Output type:
- Summary: The default; as shown in the example above.
- Detail: Typical R output, some additional information compared to Summary, but without the pretty formatting.
- ANOVA: Analysis of variance table containing the results of Chi-squared likelihood ratio tests for each predictor.
- Relative Importance Analysis: The results of a relative importance analysis.
- Effects Plot Plots the relationship between each of the Predictors and the Outcome.
OPTIONAL: Select the desired Missing Data treatment. (See Missing Data Options).
OPTIONAL: Select Variable names to display variable names in the output instead of labels.
OPTIONAL: Select Correction. Choose between None (the default), False Discovery Rate, Bonferroni.
OPTIONAL: Specify the Automated outlier removal percentage to remove possible outliers.
OPTIONAL: Select Stack data to stack the input data prior to analysis. Stacking can be desirable when each individual in the data set has multiple cases and an aggregate model is desired.
