If the random variable X follows the EBXII distribution, therth central moment of X can be given as in Equations (4)–(6). Then, the MEs are obtained by equating the first three population moments to the corresponding sample moments. However, the restriction k>−c/r for the existence of therth moment can cause certain problems. In order to overcome these problems, following the study of Shaoetal.[18], a generalized logistic distribution to the log-transformed data is derivedas follows.
