Dunn Test Bonferroni Correction gives p-value of 1. Error?

[Lucy Kay]

I did the Dunn test using the following code:

dunntest rating, by(outcome) ma(bonferroni)

I ended up getting a p-value of 1 for some pairwise comparisons, which I assume is an error since the data is not the same for any of the groups compared. How do I fix this error?

I doubt that it's an error. It's not uncommon to get a p-value of 1 for pairwise comparisons with the Bonferroni method.
