Abstract: | This paper deduced a very simple and practical formulation of least square forecast in condition of even interval observing. This new formulation can directly calculate the value of the next observing-point by using the four preceding histrical da' ta. So it can be more easily and directly used in real-time control and other fields,forecasting the dynamic trends of various data. |
