This paper is concerned with the two-parameter Weibull distribution which is widely employed as a model in life testing. Maximum likelihood equations are derived for estimating the distribution ...

The three-parameter Weibull estimation can be numerically difficult, and it usually pays off to provide good initial estimates. Therefore, you first estimate and c of the two-parameter Weibull ...

This study develops maximum likelihood estimators for the three parameter Weibull distribution based on various left and right censored data situations. For the case of single censoring from the left ...

For example, Weibull analysis can reveal the point at which a specific percentage of a population (such as a production run) will have failed, a valuable parameter for estimating when specific ...

This example considers a data set given in Lawless (1982). The data are the number of days it took rats painted with a carcinogen to develop carcinoma. The last two observations are censored. Maximum ...
