“…Several researchers have suggested confidence intervals for the mean and functions of the mean of delta-lognormal distributions, such as the traditional method, the normal algorithm, the exponential algorithm ( Kvanli, Shen & Deng, 1998 ), bootstrapping, the likelihood ratio, the signed log-likelihood ratio ( Zhou & Tu, 2000 ; Tian, 2005 ; Tian & Wu, 2006 ), GCI ( Tian, 2005 ; Chen & Zhou, 2006 ; Li, Zhou & Tian, 2013 ; Wu & Hsieh, 2014 ; Hasan & Krishnamoorthy, 2018 ; Maneerat, Niwitpong & Niwitpong, 2018 , 2019b ), MOVER ( Maneerat, Niwitpong & Niwitpong, 2018 , 2019a , 2019b ), Aitchison’s estimator, a modified Cox’s method, a modified Land’s method, the profile likelihood interval ( Fletcher, 2008 ; Wu & Hsieh, 2014 ), FGCI ( Li, Zhou & Tian, 2013 ; Hasan & Krishnamoorthy, 2018 ; Maneerat, Niwitpong & Niwitpong, 2019a ), as well as Bayesian approaches ( Maneerat, Niwitpong & Niwitpong, 2019a ). Moreover, confidence interval estimations for the variance ( Maneerat, Niwitpong & Niwitpong, 2020a , 2020b ), CV ( Yosboonruang, Niwitpong & Niwitpong, 2018 , 2019a , 2019b ), and functions of the CV ( Yosboonruang & Niwitpong, 2020 ; Yosboonruang & Niwitpong, 2020 ) of delta-lognormal distributions have been suggested, including GCI, the modified Fletcher’s method, FGCI, MOVER, the Bayesian approach, and bootstrapping.…”
