Comparisons

This table provides an overall test of the equality of survival times across groups. The test statistic is based upon the differences in group mean scores. Roughly speaking, a case's individual score is increased for each comparison in which it has the higher survival time and decreased when it has the lower survival time. The mean score for a group is the average of the individual scores for cases in the group. Since the significance value of the test is less than 0.05, you can conclude that the survival curves of at least two groups are different. Look at the pairwise tests to confirm which groups are different.

The pairwise tests for Basic service customers show that their survival curve is statistically significantly different from E-service and Plus service customers.

Similarly, the pairwise tests for Total service customers show that their survival curve is different from E-service and Plus service customers.

These results confirm the differences you saw in the survival plots, that Total service and Basic service customers have the lowest survival curves. Moreover, since the significance value of their pairwise comparison is greater than 0.05, their survival curves are not statistically distinguishable.

Lastly, the pairwise comparison between E-service and Plus service customers is statistically significant, confirming that E-service customers have a lower survival curve than Plus service customers.
