You could use -intreg- if you wanted to handle censored times within and OLS
framework. As I see it, however, you are risking mixing up cause and effect.
The effect, the predicted variable, is failure. The cause of failure is
exposure to risk. Exposure to risk is a function of
- what risk factors you are exposed to and
- how long you are exposed to them.
You can express your results in terms of median time to failure for
different groups, and this is a very useful way of doing so, but graphing
them is even more informative, since you can then show the whole time
course.
