Abbreviation: NPCR, National Program of Cancer Registries.
Excludes the Pacific Regional Central Cancer Registry. Registry did not report cases diagnosed in 2006 and is still ramping up case reporting. Low case volume distorts cost per case calculations.
Excludes NPCR registries that also receive Surveillance, Epidemiology, and End Results funding: California (San Francisco-Oakland, San Jose-Monterey, Los Angeles), Georgia (Atlanta), Kentucky, Louisiana, Michigan (Detroit), New Jersey, and Washington (Seattle-Puget Sound).
Cost per case adjusted using area wage index as noted in text previously. Log values are used.
Final model presented previously. R2 was 0.60 for this model. The following variables were dropped from the specification because of limited explanatory power or correlation between regressors: population size flags (low, medium, high); contractor flag; and North American Association of Central Cancer Registries status (gold or silver).
.001%; robust standard errors.
.05%; robust standard errors.
