"Using data [for India] on proportions of children dead...estimates of infant and child mortality are...obtained by Sullivan and Trussell modifications of [the] Brass basic method. The estimate of child survivorship function derived after logit smoothing appears to be more reliable than that obtained by the Census Actuary. The age pattern of childhood mortality is suitably modelled by [a] Weibull function defining the probability of surviving from birth to a specified age and involving two parameters of level and shape. A recently developed linearization procedure based on [a] graphical approach is adopted for estimating the parameters of the function."
利用[印度的]儿童死亡比例数据……婴儿和儿童死亡率的估计值是通过对布拉斯基本方法进行沙利文和特鲁塞尔修正而得出的。经对数平滑后得出的儿童生存函数估计值似乎比人口普查精算师得出的估计值更可靠。儿童死亡率的年龄模式通过一个威布尔函数进行适当建模，该函数定义了从出生到特定年龄存活的概率，并涉及水平和形状两个参数。为估计该函数的参数，采用了一种基于图形方法的最新开发的线性化程序。
