因此,每个班次需要安排的总人数n_i可表示为: \begin{equation} n_i = m_i + k_i = (\frac{Q_i}{25m_i+20k_i})\times \frac{1}{8} \times \frac{1}{\frac{Q_i}{T}} = \frac{T}{200} \end{equation} 通过上述公式,可以得到每个班次需要安排的总人数,从而可以得到每个班次需要的正式工人...
Forecasts of ARIMA processes are generally made using the Difference Equation form. This is the approach favoured by Box and Jenkins and most subsequent authors. The purpose of this note is to emphasise that the Integrated Form of the forecast enjoys some important advantages derived from its ...

Additionally, for cases where for the first method a low power is met, we studied the validity of prediction interval for a future value of ARIMA (0,2,1) with θ close but greater of 1, using the prediction equation and the error variance of the random walk. Keeping the forecasting ...

Additionally, for cases where for the first method a low power is met, we studied the validity of prediction interval for a future value of ARIMA (0, 2, 1) with θ close but greater of −1, using the prediction equation and the error variance of the random walk. Keeping the ...
