A Sudden death problem

[insua]

hi, i have a problem and need your help.
how can i solve the problem in weibull++ ?
"An incomplete test specimen is given, where the lifetime of planet carrierhead
screws in farm tractors was recorded. A total of 1075 tractors were
involved. After 10 failures due to broken head screws, an assessment
should be carried out with the recorded data. The running time until
breakage of the planet carrier-head screws are given:
99, 200, 260, 300, 340, 430, 499, 512, 654, 760.
The running times of the intact units at the time of the assessment are unknown."

What you will have to do is make sometype of an educated guess on the running times of the intact units and add them as suspnesions (right censored).

There are multiple ways to arrive at that "educated guess" depending on what you already know. As an example if you know the average use per month and you know the age of the population items, you can then use that as an estimate.
