“…When we consider the multivariate statistics applied to the context of steelmaking processes, studies can be found for the calculation of the mass balance of blast furnaces (Ruuska, Sorsa, Lilja & Leiviskä, 2017), estimation of the energy conservation potential in the Chinese industry (Rao, Rama, Subbaiah, Rao & Rao, 2013), early detection of segregation in continuous casting processes (Nieto et al, 2015), among others. We can also point out the use of different application methods for the analysis of multivariate statistics in steel processes, such as logistic regression in (Xu & Zhao, 2005), and robust regression methods (Mondal, 2016), for example.…”
