The Comparisons report is shown when you specify pairwise comparisons. It contains the following columns:
Factor
Shows the levels of the subject factors that you specified.
Compared 1
Shows the factor and levels for the profile variables in the first component of the comparison.
Compared 2
Shows the factor and levels for the profile variables in the second component of the comparison.
Utility 1
Shows the estimated utility of the first component for the subjects specified in the Factor column.
Utility 2
Shows the estimated utility of the second component for the subjects specified in the Factor column.
Probability 1
Shows the predicted probability that the first component is preferred to the second for the subjects specified in the Factor column.
Probability 2
Shows the predicted probability that the second component is preferred to the first for the subjects specified in the Factor column.
Odds 1
Probability 1 divided by Probability 2.
Odds 2
Probability 2 divided by Probability 1.
Comparison Difference
Utility 1 minus Utility 2.
Standard Deviation
The sample standard error of the estimated Comparison Difference.
