“…The statistical methods are the most used to explain the variations in efficiency. Among these methods, for example, the non-parametric tests (Ahmad and Rahman, 2012;Hacini and Dahou, 2018); the ordinary least square (OLS) regression (Goswami et al, 2019;Mansour and El Moussawi, 2020); the Tobit regression (Achi, 2020;Tandon et al, 2014); the Bootstrapped IJPPM 72,5 truncated regression (Assaf and Barros, 2011;Gulati and Kumar, 2017); and the logistic regression (Adusei, 2016;Kumar and Gulati, 2008). In regression analysis, efficiency scores computed by the DEA model is the dependent variable and the explanatory variables are the independent ones.…”
