人口统计数据系统误差的检验

The Test of Systematic Errors in Demographic Data

人口统计数据的系统误差,常常表现在特定的年龄尾数上数据观测值对真值的偏离。讨论了现行的人口年龄数据质量检验方法,指出了存在的问题,提出了可使用人口函数年龄变动的符号分布来检验人口数据是否存在系统误差,并用实际数据作了验证。经过比较,这种新的检验方法比以往的方法更有效。

The systematic errors of demographic data usually manifest the deviation of the observed value from the true value of the specific age mantissa data. This article discusses the current data - quality testing methods of population age data, and points out the problems. The article also provides ways to test the existence of a systematic error using the sign distribution of the age change in the population function and gives an actual verification which shows the new testing method is more effective.
