Hi All,
I have data in the following format:
Inspection #failures
Month/Year
01/99 5
02/99 20
06/99 3
01/02 3
for 11 years ... the prob of failure on demand per month pfd is #Total
failures / sample size(=total components * 11yrs * 12months).
I am required to cross-check pfd by other means.
Can I fit a weibull or lognormal plot to this count data and find the
failure probability or reliability from this data? exact failure times are
not known..only the number of failures in the month is known. please
suggest an appropriate method / R code.
Thanks,
Tims
