Hi Doug, Got it! Sorry that I keep forgetting this. So it’s an exponent statistic.
The reviewers asked for a statistic and df. I think I can convert it to a Z-statistic so it’s more “conventional”. I also noticed that qdec provides a df when I set up the model. It is valid to use that df to derive the t-statistic?
