residual variance 中文意思是什麼
residual variance
解釋
殘余方差-
We analyse the dispersion of stock returns and have the tests of serial correlation. the results show that the trading mechanism has a significant effect on a number of characteristics of stock returns. first, the distribution of open - to - open returns has greater variance than that of close - to - close returns. second. the serial correlation pattern is quite different in the two return series. the open - to - open returns have negative autocorrelation coefficient, but the close - to - close returns is positive. further, employing an arma ( 1, 1 ) model we find that in the opening. returns exhibit higher residual noise and stronger dependence on past returns, reflecting stronger deviations from the random - walk form of the market efficiency hypothesis
主要表現為：一，開盤收益序列比收盤收益序列具有更大的方差。二，兩種收益序列的序列相關形式不同，開盤收益序列表現為負相關，而收盤收益序列表現為正相關。而且我們通過arma （ 1 ， 1 ）模型的進一步檢驗，發現開盤收益序列比收盤收益序列具有更大的殘差，更依賴于過去的收益序列，也更偏離於市場有效的隨機遊走形式的假設。 -
On base of the data analysis, three - dimensional tide - induced residual currents, the wind - driven and thermohaline currents in the bohai sea are diagnostically computed with an orthogonal curvilinear grid system, by means of a three - dimensional ecomsed model. the winter and summer thermohaline structure and circulation characteristics in bohai sea are analysed, and the circulation variance is discussed preliminarily. the tides and tidal currents in bohai sea are well reproduced
在資料分析的基礎上，應用三維斜壓ecomsed模式對渤海的潮致余流、風生環流和密度環流進行了診斷計算，分析了渤海冬夏季的溫鹽場結構和對應環流的特徵，並對渤海上述幾個不同時期的環流變異進行了初步的分析和探討。 -
Aesthetic appearance is one of the most important criteria used by consumers in judging clothing wear performance. bagging is a kind of three - dimensional residual deformation that deteriorates garment appearance during wear and caused dissatisfaction. to understand the psychophysical mechanisms of fabric bagging perception, a method of subjectively evaluating this behavior is developed by using a series of photographs taken from bagged fabric samples. both ranking and rating scales are used as the psychological scales. the two scales are highly correlated with each other, but the rating scale provides more information than the ranking scales and can indicate perceived differences between fabrics. a linear relationship between subjective perceptions and measured residual bagging height shows that perception of fabric bagging follows stevens ? power law. residual bagging height contributes up to 94 % of the total variance in the perception of fabric bagging. the rest of the variation may be attributed to anistropic behavior during the bagging process
美觀是消費者日常服裝穿著功能中最重要的指標之一.起拱是一種外衣穿著中引起變化，令人不滿的三維殘余變形.一種主觀評價方法是從一系列起拱織物的照片來理解心理物理學規律，採用優劣排序等級和優劣評判等級兩種方法用於心理評價標度.這兩種等級互相間緊密相關，但評判等級比排序等級包含更多的信息，可以更好地區分出兩種織物間的差異.主觀評價結果與測量得到的殘余起拱高度之間線性相關，表明了織物起拱特性符合斯特藩指數定律.殘余起拱高度對織物起拱特性總方差的貢獻在94 %以上.其它可能是起拱時各向異性因素引起的 -
We propose an algorithm, which integrate the shift invariance of redundant discrete wavelet transformation ( rdwt ) and the flexibility of multi - resolution motion estimation, to overcome the shift variance of dwt and get the precise motion vector. under the different code parameter, we take the proposed algorithm compared to several present algorithms, and experiment results have shown that proposed algorithm could leave less energy in the residual frames, get more precise motion vector and better reconstructed frames
文章最後在不同的編碼參數下，將所提演算法與兩種傳統小波域運動估計演算法作比較，根據實驗所得數據分析，發現所提演算法在性能上要優于另外幾種演算法，具體體現在運動估計后所得殘差幀能量更小，重構幀客觀與主觀質量更高。 -
Known susceptibility genes account for less than 25 % of the familial risk of breast cancer, and the residual genetic variance is likely to be due to variants conferring more moderate risks
大家知道乳腺癌的家族危險性的小於25 %是由於易感基因，而剩餘的遺傳變異更多是由於變異體，而這種變異引起更多的風險。
