Özet

In this paper, we focused on testing for the equality of several log-normal means since the log-normal distribution is one of the most common distributions for analyzing positive and right-skewed data. Recently, many researchers have proposed a lot of methods based on likelihood-based methods, generalized pivotal-based methods, and bootstrap-based methods for this case. Apparently, since there is not an exact result regarding which test is better than the others in which cases, our goal shed light on this important issue. For this reason, we investigate these methods and compare them with each other by a simulation study.
