Jeanne,
a year ago or so I wrote a program called -cqreg-,
which is a straightforward generalization of -clad-
to variable censoring. I never published the program
because I do not know whether it is any good or not
(i.e. whether the estimator produces consistent
results under reasonable assumptions). If you contact
me offline ([email protected]) I will send you
the program.
