A Bartlett-type correction for the subject-years method in comparing survival data to a standard population


  • Tu, Dongsheng
  • Gross, Alan J.


A Bartlett correction is derived to improve the accuracy of the subject years method, which is used to compare the mortality experience of the population being studied to that of a known population in medical follow up studies. The actual type 1 errors and powers of the Bartlett corrected test are compared with that of the original test by Monte-Carlo simulations.
