Hi, so I've been searching the web a while for a real example or procedure to get hazard rates from actual data but all I can come up with are theories/derivations, which have not been helpful. I'm trying to do the basic calculations of hazard rates at different points in time from a sample set of data. I would assume the Weibull or Normal distribution would be reasonable to use but for example, let's say I have failures at the following times:

Failures
101
101
201
201
201
301
301
301
301
301
401
401
401
401
401
401
501
501
501
501
501
601
601
601
601
701
701
701
801
801
901

How do I setup a table to calculate the hazard rates at 100, 200, ... , 1000? If someone could just lay out the steps needed do to this that would be sooo helpful. I can use excel to get CDF/PDF but they don't seem to translate into actual failure rates...any help or insight would be greatly appreciated. ALSO, is there a good way to do this exact same thing but instead of having "real events" to go by, I'm only given an average time to failure (and let's say a SD at 50% of the average time to failure). Thanks!
