Hello,
There is a research of checking failures occurances of people.
The information includes the following fields:
Entrance time (in YYMM format)
Nr_people (Number of people enter the research in this month)
time0_to_time1 (Number of people who fail between time 0 and time 1 since they enter the research)
time1_to_time2 (Number of people who fail between time 1 and time 2 since they enter the research )
time2_to_time3 (Number of people who fail between time 2 and time 3 since they enter the research )
and so on.
As you can see for each group of people there is a different number of months that they were exposed for failure.
For example:
people who joined in 2101 are exposed for failure during 6 months.(till 2106)
people who joined in 2101 are exposed for failure during 5 months.(till 2106)
and so on.
I want to calculated the cumulative probability of failure in this research.
I know to calculate it for each group (time entrance)
but the question is how to calculate it for the whole people in the research.
Hello,
If you enter :
exposure adjusted incidence rates exposure adjusted event rates
as search terms on :
, you will already get a few hints.
Thanks,
Koen
