(Reg Sci Urban Econ 40(2–3):106–115, 2010) introduce a nonparametric test of spatial dependence, called SG(m). The test is claimed to be consistent and asymptotically Chi-square distributed. Elsinger (Reg Sci Urban Econ 43(5):838–840, 2013) raises doubts about the two properties. Using a particular counterexample, he shows that the asymptotic distribution of the SG(m) test may be far from the Chi-square family; the property of consistency is also questioned. In this note, the authors want to clarify the properties of the SG(m) test. We argue that the cause of the conflict is in the specification of the symbolization map. The discrepancies can be solved by adjusting some of the definitions made in the original paper. Moreover, we introduce a permutational bootstrapped version of the SG(m) test, which is powerful and robust to the underlying statistical assumptions. This bootstrapped version may be very useful in an applied context. 000060723 536__ $$9info:eu-repo/grantAgreement/ES/MINECO/ECO2012-36032-C03-01$$9info:eu-repo/grantAgreement/ES/MINECO/ECO2012-36032-C03-03 000060723 540__ $$9info:eu-repo/semantics/openAccess$$aAll rights reserved$$uhttp://www.europeana.eu/rights/rr-f/ 000060723 590__ $$a1.175$$b2015 000060723 591__ $$aGEOGRAPHY$$b40 / 77 = 0.519$$c2015$$dQ3$$eT2 000060723 592__ $$a0.812$$b2015 000060723 593__ $$aGeography, Planning and Development$$c2015$$dQ1 000060723 593__ $$aEarth-Surface Processes$$c2015$$dQ2 000060723 655_4 $$ainfo:eu-repo/semantics/article$$vinfo:eu-repo/semantics/acceptedVersion 000060723 700__ $$aMatilla-García, M. 000060723 700__ $$0(orcid)0000-0002-7384-9166$$aMur, J.$$uUniversidad de Zaragoza 000060723 700__ $$aPáez, A. 000060723 700__ $$aRuiz, M. 000060723 7102_ $$14000$$2415$$aUniversidad de Zaragoza$$bDpto.
