Dear Allstaters
Could anyone in the group suggest a reference for a procedure for the
confidence interval calculation for the Weibull NHPP (power law) process
where the data is aggregated into a series of time intervals (not
necessarily equal) with N(0), N(1),... events in each interval. I am looking
for a reference that derives the equations for this.
I found a paper by Larry Crow (Technometrics Vol 24, No 1 Feb 1982) which
treats the cases of failure and time truncated data but he does not treat
aggregated data.
Any help very much appreciated
Thank you.
