摘要

PPROBLEM TO BE SOLVED: To more surely than ever provide a method of estimating parameters for time-series, method of predicting data from the estimated parameters, a parameter estimation device, a data prediction device, a computer program, and a recording medium. PSOLUTION: A time-series comprising a plurality of data is read (S1), white noise is generated (S2), a white noise variance SBe/SBSP2/SPis calculated (S3), and information required for calculation is calculated where the self-correlation function of the white noise with a lag of 0 is SBe/SBSP2/SP, the self-correlation function of the white noise with a log other than 0 is O, and the value of the correlation function of the time-series to the value of the white noise far ahead of the time-series is 0 (S4), and the parameters of an ARMA model to which the time-series is adopted are calculated (S5). Whether the calculated parameters are converged or not is determined (S6), and when the parameters are not converged, new white noise is generated from the calculated parameters by using the equation of the ARMA model (S4), and the calculation is repeated until the parameters are converged.

要解决的问题:比以往更加确定地提供一种估计时间序列参数的方法,一种根据估计参数预测数据的方法,参数估计设备,数据预测设备,计算机程序和记录中。

解决方案:读取包含多个数据的时间序列(S1),生成白噪声(S2),计算白噪声方差 e 2 (S3),计算计算所需的信息,其中滞后为0的白噪声的自相关函数为 e 2 ,即对数为0以外的白噪声为O,时间序列与该时间序列前面的白噪声值的相关函数值为0(S4),ARMA的参数计算采用时间序列的模型(S5)。确定所计算的参数是否收敛(S6),并且当参数不收敛时,通过使用ARMA模型的方程从所计算的参数生成新的白噪声(S4),并且重复计算直到参数已收敛。
