Cubic Splines and Histosplines
1991In chapter 2 we provided an explanation for the failure of many methods intended to find time- and age-dependent mortality rates from stage structured population data. It was also suggested that an effective method of mortality estimation would be a more local method than those so far suggested.

A spline function is a curve constructed from polynomial segments that are subject to conditions of continuity at their joints. The chapter describes the algorithm of the cubic smoothing spline and its use in estimating trends in time series. Considerable effort has been devoted over several decades to developing the mathematics of spline functions ...

A cubic polynomial curve in the xy-plane, (x1 (t), x2(t)), whose cubic term has a coefficient of 0 reduces to a parabola in this special case; but a cubic polynomial cannot represent other conic section curves such as a circular arc, an elliptic arc, or a segment of an hyperbola. It is an interesting fact, however, that an elliptic or hyperbolic arc in
