Comment on “An extended STIRPAT model-based methodology for evaluating the driving forces affecting carbon emissions in existing public building sector: evidence from China in 2000–2015” by Ma et al. (2017)

Abstract

This contribution highlights that the paper presented by Ma et al. (Nat Hazards 89(2):741–756, 2017) presents VIF lower than 1 which does not coincide with the natural definition of VIF and clarifies how to detect collinearity after the application of the ridge estimator and how the results can be analyzed. Thus, this contribution allows empirical conclusions to be founded on a rigorously well-applied methodology.
