Abstract :
The extended three-parameter Burr XII (EBXII) distribution has recently attracted considerable attention
for modeling data from various scientific fields since it yields a wide range of skewness and kurtosis
values. However, it is well known that the parameter estimates have significant effects on the success of
a distribution in real-life applications. In this study, modified moment estimators (MMEs) and modified
probability-weighted moments estimators (MPWMEs) are used to estimate the parameters of the EBXII
distribution. These two considered estimators are also compared with the commonly used maximumlikelihood,
percentiles, least-squares and weighted least-squares estimators in terms of bias and efficiency
via an extensive numerical simulation. The MMEs and MPWMEs are observed to perform well in varying
sample cases, and the simulation results are supported with application through a real-life data set.
