Web在R估计ARIMA模型时，它会采用极大似然估计(maximum likelihood estimation)。 该方法通过最大化我们观测到的数据出现的概率来确定参数。 对于ARIMA模型而言，极大似然估计和最小二乘估计非常类似，最小二乘估计是通过最小化方差而实现的： \[ \sum_{t=1}^T\varepsilon_t^2. WebARIMA (1,1,1) Model A time series modelled using an ARIMA (1,1,1) model is assumed to be generated as a linear function of the last 1 value and the last 1+1 random shocks generated. The data is different 1 time. Differencing the model once does not make it stationary enough for the ARIMA model. Hence, we shall try ARIMA (2,2,1). ARIMA …
