Re: Weibull Distribution but with a varied cycle time

Thanks,

Basically I'd like to do it myself, as i'll learn that way, but
basically the device will be in an automated rig to collect the data
to a computer so i dont need to sit there for hours, and i can let it
run over a week or more 24/7 if need be.

The device powers on and supplies voltages at set amounts (although
they could be varied), so things like the current in and the voltages
out, can be checked to ensure that the values are within tolerance.

But occasionally it has been know for the units to fail on power-up or
into there run time, so i want to get some stats on that

is a failure on power-up classed as censored data? does this look like
a good case for time-to-failure?

its really both power-up failure and time to failure im interested in,
prehaps something simple like exponetial distribution would be useful
for a failure on power-up?

Thanks

David
