Column 1 is the number of nearest neighbors considered (k = 1,...,10, 15, 25, 50, 75); Qk is the value of the global statistic for evaluating clustering of residential histories of cases over the entire study period and study area; p(Qk|ind) is the probability of Qk under the null hypothesis of independence that assumes the cases and controls have equal probability of being a case; p(Qk|cov) is the probability of Qk accounting for smoking, age, gender, education and race; 1476-072X-5-32-i1http://www.w3.org/1998/Math/MathMLQkFMathType-MTEF MathType@MTEF@5@5@+=feaafiart1ev1aaatCvAUfKttLearuWrP9MDH5MBPbIqV92AaeXatLxBI9gBaebbnrfifHhDYfgasaacH8akY=wiFfYdH8Gipec8Eeeu0xXdbba9frFj0=OqFfea0dXdd9vqai=hGuQ8kuc9pgc9s8qqaq=dirpe0xb9q8qiLsFr0=vr0=vr0dc8meaabaqaciaacaGaaeqabaqabeGadaaakeaacqWGrbqudaqhaaWcbaGaem4AaSgabaGaemOrayeaaaaa@3078@ is the focused statistic for assessing clustering about the business address histories of the 268 industries, and is evaluated for all industries simultaneously; p(1476-072X-5-32-i1http://www.w3.org/1998/Math/MathMLQkFMathType-MTEF MathType@MTEF@5@5@+=feaafiart1ev1aaatCvAUfKttLearuWrP9MDH5MBPbIqV92AaeXatLxBI9gBaebbnrfifHhDYfgasaacH8akY=wiFfYdH8Gipec8Eeeu0xXdbba9frFj0=OqFfea0dXdd9vqai=hGuQ8kuc9pgc9s8qqaq=dirpe0xb9q8qiLsFr0=vr0=vr0dc8meaabaqaciaacaGaaeqabaqabeGadaaakeaacqWGrbqudaqhaaWcbaGaem4AaSgabaGaemOrayeaaaaa@3078@|ind) is the probability of 1476-072X-5-32-i1http://www.w3.org/1998/Math/MathMLQkFMathType-MTEF MathType@MTEF@5@5@+=feaafiart1ev1aaatCvAUfKttLearuWrP9MDH5MBPbIqV92AaeXatLxBI9gBaebbnrfifHhDYfgasaacH8akY=wiFfYdH8Gipec8Eeeu0xXdbba9frFj0=OqFfea0dXdd9vqai=hGuQ8kuc9pgc9s8qqaq=dirpe0xb9q8qiLsFr0=vr0=vr0dc8meaabaqaciaacaGaaeqabaqabeGadaaakeaacqWGrbqudaqhaaWcbaGaem4AaSgabaGaemOrayeaaaaa@3078@ under the null hypothesis of independence; p(1476-072X-5-32-i1http://www.w3.org/1998/Math/MathMLQkFMathType-MTEF MathType@MTEF@5@5@+=feaafiart1ev1aaatCvAUfKttLearuWrP9MDH5MBPbIqV92AaeXatLxBI9gBaebbnrfifHhDYfgasaacH8akY=wiFfYdH8Gipec8Eeeu0xXdbba9frFj0=OqFfea0dXdd9vqai=hGuQ8kuc9pgc9s8qqaq=dirpe0xb9q8qiLsFr0=vr0=vr0dc8meaabaqaciaacaGaaeqabaqabeGadaaakeaacqWGrbqudaqhaaWcbaGaem4AaSgabaGaemOrayeaaaaa@3078@|cov) is the probability of 1476-072X-5-32-i1http://www.w3.org/1998/Math/MathMLQkFMathType-MTEF MathType@MTEF@5@5@+=feaafiart1ev1aaatCvAUfKttLearuWrP9MDH5MBPbIqV92AaeXatLxBI9gBaebbnrfifHhDYfgasaacH8akY=wiFfYdH8Gipec8Eeeu0xXdbba9frFj0=OqFfea0dXdd9vqai=hGuQ8kuc9pgc9s8qqaq=dirpe0xb9q8qiLsFr0=vr0=vr0dc8meaabaqaciaacaGaaeqabaqabeGadaaakeaacqWGrbqudaqhaaWcbaGaem4AaSgabaGaemOrayeaaaaa@3078@ accounting for smoking, age, gender, education and race. |
