Abstract
, it is investigated whether moderator variables are effective on LhV estimation with proximate analysis data collected from forty-one lignite basins in different regions of Turkey, and a moderator variable analysis (MVA) model is developed to be used for the prediction of LhV. As a result of the study, it is found that the proposed MVA model is in accordance with observation values (coefficient of determination R 2 = 0.951), and absolute and standard errors are also small. Therefore, it is concluded that the use of MVA to estimate the LhV of Turkey’s lignite is found to be more statistically meaningful.
期刊介绍：
Gospodarka Surowcami Mineralnymi – Mineral Resources Management is a journal of the MEERI PAS and the Committee for Sustainable Mineral Resources Management of the Polish Academy of Sciences. The journal has been published continuously since 1985. It is one of the leading journals in the Polish market, publishing original scientific papers by Polish and foreign authors in the field broadly understood as the management of mineral resources. Articles are published in English. All articles are reviewed by at least two independent reviewers (the Editorial Board selects articles according to the “double-blind review” principle).
