Maximum Likelihood Performance of Mean Time to Failure for Right-Censored Data
In this paper failure times following Weibull, exponential and log-normal distribution are considered. The parameters of these distributions are estimated by the maximum likelihood method and these values are used to estimate other quantity of interest such as Mean Time to Failure (MTTF), an im...

| Summary: | In this paper failure times following Weibull,
exponential and log-normal distribution are considered.
The parameters of these distributions are estimated
by the maximum likelihood method and these values
are used to estimate other quantity of interest such as
Mean Time to Failure (MTTF), an important function
in a reliability analysis. This study is to look at the
performance of maximum likelihood estimate (MLE)
under various conditions by considering varying sample
size and percentage of censored data. The performance
is quantified from the study. |
