This data set contains the number of incident brain cancer cases in the 32 counties of New Mexico, USA, and each year of the period 1973-1991, and the location of Los Alamos National Laboratory. In addition, the data set also includes for each county and year information about the expected cases, the Standardized Morbidity Ratio (SMR), the FIPS...
brainst: A STFDF object containing the following information for each county and year:
|Observed||Number of observed brain cancer cases|
|Expected||Number of expected brain cancer cases. Standardisation is done taking the whole time-period and not year-ly to keep any temporal trend.|
|SMR||Standardized Morbidity Ratio (observed/expected)|
|ID||ID (from 1 to 32)|
|IDLANL||Inverse distance to Los Alamos National Laboratory|
|IDLANLre||Re-scaled Inverse distance to Los Alamos National Laboratory (i.e., IDLANL/mean(IDLANL))|
