摘要：The main concern of this paper is to derive the fuzzy estimators for the two-parameter Log-logistic distribution. The TL-moments, L-moments and LQ-moments formulas are obtained for the Log-logistic distribution. Also, the estimation of these parameters is considered using the maximum likelihood method, the TL-moments, L-moments and LQ-moments. Furthermore, a numerical comparison is considered between all these estimators for the Log-logistic distribution.
