An efficient Statistical Analysis System computer program for the exact stratification of person-years is described, in order to determine the expected number of deaths or cases of diseases in a cohort for the calculation of standardized mortality ratios or standardized morbidity ratios. A comparison of this program with Macaluso's "Method B" program shows that the speed of the former is considerably faster than that of the latter, when the widths of the categories defined by all of the time factors are identical.
描述了一个高效的统计分析系统计算机程序，用于对人年进行精确分层，以便确定队列中预期的死亡人数或疾病病例数，用于计算标准化死亡率或标准化发病率。将该程序与马卡卢索的“方法B”程序进行比较表明，当所有时间因素定义的类别宽度相同时，前者的速度比后者快得多。
