Thanks for the tip, Maarten.

In an example, Williams ignores the p-values for the cut points ("thresholds"), and neither cut point is statistically significant at the .05 level. I guess that's an implicit endorsement for the notion that the p-values for cut points don't matter.

I've found a number of helpful discussions on the web and in texts of how the cut points should be interpreted, but none comment on p-values (or confidence intervals) for the cut points.

Rich Williams has in his handouts a discussion on the interpretation
of the thresholds (He mainly uses SPSS (or however it is called now)
but also shows output from Stata), the link is:

Hope this helps,
