内推法的中文解释
指根据已知的系列数值推算出一个在已知数值之间的数值. 内推法假定数值之间存在某种明确的关系,不是一种精确的推算法,但可用于估算债券价格和收益率。内推法分三种类型:线性内推法、对数内推法和立方内推法。参见Extrapolation(外推法)。
Interpolation的英文解释
The process of determining a rate (or other variable) that lies between a
series of known rates. Interpolation works on the
assumption that a certain
percentage change that applies generally can be
applied to calculate a
specific variable. It is a generalisation, but can be used to
estimate bond prices and yields. Three types of interpolation exist: linear, logarithmic and cubic
