Abstract The closeness-of-fit of two-parameter Brass model life-tables to English life-tables is examined. This is done for various life-table functions and various criteria of best fit. Reproductions of computer output give full details of the fits for typical cases from the large selection of cases examined. It was found that the equations to be solved to find the best fit were intractable and the paper gives a simple method of finding an approximate solution to these equations.
摘要 本文考察了双参数 Brass 生命表与英国生命表的拟合优度。通过不同的生命表函数和最佳拟合标准进行了这项研究。计算机输出的复制品为经过大量案例检验的典型案例的拟合提供了详细信息。研究发现，找到最佳拟合所需求解的方程难以处理，因此本文提出了一种简单的方法来求解这些方程的近似解。
