Influential observations in ordered logistic regression

[RonD McDowell]

I have some ordered logistic regression models and am doing some diagnostics. I have been working through various strategies from Long and Freese's Regression book which have been very helpful. However I am also interested in considering potentially influential observations. In linear regression, for example, diagnostics such as leverage, Cook's distance etc. are readily available. I haven't found anything to date about examining influential observations from ordered logistic regression in STATA or elsewhere, and wondered if anyone else had?
