equal variance
解釋
等方差性-
Equal variance test
等差異檢驗 -
One of the important hypotheses of classical linear regression model is that the random disturbances have equal variance
經典線性回歸模型的一個重要假設就是回歸方程的隨機擾動項u _ i ，具有相同的方差，也稱同方差性。 -
As goldfeld - quandt test can only be applied to one independent variable, it is generalized in the second section. it shows that, in multivariate situation, the data can be arranged according to their principle components. but there should be a premise : the disturbances of the lower data group should have equal variance and those of the higher data group have the same variance
由於戈德菲爾德-匡特檢驗方法只適用於一個自變量，因此，本文對g - q檢驗進行了推廣，說明在多變量的情況下，可以利用主成分對樣本數據進行排序，並強調使用戈德菲爾德-匡特檢驗的前提：低樣本組各觀察值的擾動項必須具有同方差性；高樣本組各觀察值的擾動項也必須具有同方差性，否則，檢驗的結果可能是錯誤的。 -
The summer typical persistent circulation patterns over eurasia mid - high latitude have obvious decadal variance : the occurrence frequency of type c course is relatively high from the 1960s to the 1970s, and the occurrence frequency of type e course increased while the type c course has not appeared in the 1980s, and two kinds of course were about equal frequently in the 1990s
夏季歐亞中高緯典型持續流型有明顯的年代際變化， 60 、 70年代c型過程出現頻數較高， 80年代e型過程出現頻數增高而c型過程未出現， 90年代兩類過程頻數相當。即1980年前後有明顯的差異。 -
From 1959 to 2000, the occurrence frequency of summer typical persistent circulation pattern e is about equal to that of type c, and the occurrence frequency of type w is relatively less ; the occurrence frequency of pattern e and c ' s course is most high in june ; the course of pattern e and c exist certain decadal variance or phased characteristic
1959 ? 2000年夏季歐亞中高緯500hpa持續流型e 、 c型發生頻數相當， w型發生頻數相對較少； e 、 c型過程在6月發生頻次最高： e 、 c型過程的發生存在一定的年代際變化或階段性特徵。 -
However, two - stage estimates of regression coefficients corresponding to these two estimates have approximate equal mean square error. for testing linear hypothesis about regression coefficients, banerjee and magnus ( 1997 ) studied the sensitivity of f - test sta, tistic ( fgls ( ) ) based on generalized least square estimate caused by variance parameter in general case and proposed sensitivity statistic and its distribution
關于回歸系數的線性假設檢驗問題， banerjee和magnus （ 1997 ）在一般情況下從理論上研究了方差參數對基於廣義最小二乘估計的f -檢驗統計量（ f _ （ gls ） （ ） ）的種種影響，提出了敏感性的概念，並給出敏感統計量的形式及其分佈。 -
The importance of the interdecadal variation is similarly equal to that of interannual change in nespa variance constitution. 3 ) nespa is divided into 6 regions, and interdecadal variation is more significant in southeast than in northwest area
3 ）降水異常可劃分為6個主要異常區，其年代際變化的顯著性東南部（南、東、中區）高於西北部（西、北、西北區） 。 -
A algorithm of shot coarse classification is proposed, firstly, key frames are extracted in equal interval in a shot ; then for a frame, dominant colors are obtained by hue, furthermore, the variance of dominant colors and ratio of clustered colors are computed, by which the corresponding frame could be classified into playing or non - playing frame, finally, a shot could be classified by the percentage of playing frames
2 .在鏡頭粗分類中，首先在每個鏡頭內等間隔地提取關鍵幀，隨后得出主顏色序列，並對主顏色序列進行方差統計和聚類顏色比率的計算，最後依據比賽幀比率來進行鏡頭分類。
