例句与用法 | 1. | Square number couple theory
方形数偶理论
| | 2. | Thus , it constituted from return to return the condition difference square number model
这样就构成了自回归条件异方差模型。
| | 3. | And this at any time the square number of a variety is the line combination that is the limited item news number ’ s square
并且这个随时间变化的方差是过去有限项噪声值平方的线性组合。
| | 4. | From this basic thought we can see , because of the square number of now time news voice is the limited item square number to returned to return in the past , it ’ s means that the motion of the news voice have the certain memory , therefore , if in past every moment the square number of the news voice differed to become big , so the square number of the news voice differed to usually also come after it to
从这个基本思想中可以看出,由于现在时刻噪声的方差是过去有限项噪声值平方的回归,也就是说噪声的波动具有一定的记忆性,因此,如果在以前时刻噪声的方差变大,那么在此刻噪声的方差往往也跟着变大;如果在以前时刻噪声的方差变小,那么在此刻噪声的方差往往也跟着变小。
