从理论上考虑，导出了一个用于拟合癌症患者精算生存曲线的双参数函数。该函数适用于两组数据，一组来自乳腺癌患者，另一组来自胃癌患者。每组根据有无转移再细分。所得到的拟合非常好，除了某些系统偏差，这些偏差从一组数据到另一组数据是不一致的。预期寿命由参数估计计算得到。同时考虑了图解法和最小二乘法的拟合。
A two parameter function for fitting actuarial survival curves from cancer patients is derived from theoretical considerations. The function is fitted to two sets of data, one from patients with breast cancer and one from patients with stomach cancer. Each set is subdivided according to the presence or absence of metastasis. The fits obtained are quite good except for certain systematic deviations which are not consistent from one set of data to the next. Life expectations are calculated from the parameter estimates. Both graphical and least squares methods of fitting are considered.
