[R] Ordinal regression with some categories combined for some data

[Frank Harrell]

This does seem to be a good situation for ordinal regression.  The R rms 
package's orm function allows for thousands of categories in Y. But it 
doesn't handle censoring.

This discussion would be better for stats.stackexchange.com
