上四分位數是25的觀察值位於其上的值。The standard error of estimate, on the other hand, measures the variability, or scatter, of the observed values around the regression line.
而估計值的平均誤差，卻是度量觀察值圍繞著回歸直線的變化程度或分散程度。Observed mean failure rate
平均故障率的觀察值Dispersion refers to the spread of the data, that is the extent to which the observations are scattered.
離散性是指數據的分散程度，即觀察值散布的范圍。In other words, an estimate is a specific observed value of a statistic.
就是說，估計值是指統計量的一個具體觀察值。If the observations used in the analysis extend back in time for several years, the resulting regression line may be too steep.
如果在分析中使用的觀察值擴大到幾年以前，那麼推導出的回歸直線就會可能太懸殊。Sufficiency and effect in the general gauss - markoff model with linear transformations
廣義線性模型的充分性及變換觀察值的影響Note the results are slightly different from those in the textbook, possibly because of rounding off errors, and because one obs. is missing in the data
注意，我們的結果與書上的結果有細微差異，可能是由於舍入誤差的存在，而且有一個觀察值在數據中缺失。However in most economic phenomena, this kind of hypothesis is not necessary true. sometimes the disturbances vary with the observations. this is called heteroscedasticity
但在大多數經濟現象中，這種假設不一定成立，有時擾動項u _ i的方差隨觀察值的不同而變化，這就是異方差性。And the dynamics model with different experiment data has further been validated to show a high degree of fitness in case of prediction and observation with the less average relative errors
模型的檢驗結果表明，模擬值與觀察值之間具有較高的符合度，平均相對誤差較小。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。This approach, using elliptical influence functions, involves the optimum blending of observations from a monitoring network with gridded pollution fields predicted by the complex air quality model tapm
