论文四参数正弦波曲线拟合的快速算法，文中给出算法及算法实现程式(Papers four-parameter sine wave curve fitting of the fast algorithm, the text is given algorithm and algorithm programs)

Inclan和 Tiao提出了迭代累积平方和算法（Iterative Cumulative Sums of Squares，ICSS）。该算法假定均值残差服 从正态独立同分布，通过构造刀统计量，对时间序列中的多个方差结构性变点进行测量。(Inclan and Tiao proposed the iterated cumulative squared sum algorithm (Iterative Cumulative Sums of Squares). The algorithm assumes that the mean residuals are normally independent and identically distributed. By constructing the tool statistics, several variance structural change points in time series are measured.)
