skewed distribution 解釋
非正態分佈
  • skewed : 傾斜的
  • distribution : n 1 分配,分發,配給;分配裝置[系統];配給品;配給量;【經濟學】配給方法,配給過程;分紅;【法律...
  1. In a negatively skewed distribution, the values are concentrated at the right end of the horizontal axis.

    在負傾斜分佈中,數值集中在橫軸的右端。
  2. The distribution was skewed toward the lower energy values.

    這種正整分佈向較低的能量偏移。
  3. It should be either approximately normal, bimodal, or skewed distribution.

    它表現為近子態的,雙態的或者偏態的分佈。
  4. As the distribution becomes wider they also tend to become skewed with a longer tail towards larger drop sizes.

    當分佈變寬時,它們往往變得不對稱,向較大的液滴尺度一端伸延得更長。
  5. If you a have a column that has a skewed data distribution, a histogram on it and if you are using bind variables against that column you may suffer from the same problem

    大致意思是,綁定變量的窺視,在你的某欄位有不均衡的數據分佈,又有柱狀圖的情況下,首次執行的語句生成了對其有利的執行計劃,它會將計劃帶個所有後面的語句,不管後面語句的執行時間會花費多久
  6. The surface panel method has been applied to predict the hydrodynamic performance of highly skewed propeller. the surface of propeller and its trailing vortex are discreted by a number of small hyperboloidal quadrilateral panels with constant source and doublet distribution. for highly skewed propeller, the conventional method generating grid oriented along constant radii will result in a high aspect ratio and a high skewness and a twist panel near the propeller tip on blade surface, which result easily in incorrect calculation results of velovity on blade surface, even in iteration divergence and calculation failure. a “ non - conventional grid ” is developed to acoid these problems. this grid can effectively solve the problem of the calculation and convergence for highly skewed propeller. the non - linear kutta condition of equal pressure on upper and lower at the trailing edge is executed by the iterative procedure. by sample calculating, the obtained results are satisfied the experimental data

    採用面元法預報大側斜螺旋槳水動力性能,螺旋槳表面及尾渦面離散為四邊形雙曲面元,每個面元上布置等強度源匯和偶極子分佈.對于大側斜螺旋槳而言,槳葉表面採用常規的等半徑網格劃分方法在近葉梢處將導致大展弦比、大側斜和扭曲面元,這容易使槳葉表面速度的計算結果不正確,甚至會導致迭代過程發散及計算失敗.文中建立了一種「非常規網格」劃分方法,能有效地解決大側斜螺旋槳的計算和收斂問題.槳葉隨邊處通過迭代實現非線性等壓庫塔條件
  7. The distributions studied are normal distribution, student - t distribution, skewed student - t distribution and general error distribution. besides this, considering the conditional heteroskedasticity of the time serial in financial market, apply the garch model into the estimation of var

    在此基礎上,研究了證券市場上時間序列收益率波動的條件異方差性,考慮中國證券市場的風險特徵,將garch系列模型與var模型相結合,構造了基於不同分佈條件下的var模型。
  8. It is revealed that the rtt distribution is best fitted by a constant plus a " skewed right " gamma distribution. the adjacent and near - adjacent delays in the time series are linearly dependent rather than random. it is also indicated that there are only weak or no nonlinear correlations among rtt observations

    分析表明rtt時間序列與一個常數加右偏的分佈極其相符合;在時間序列中相鄰的及相近的時延之間是線性相關而不是不相關的;也可以看到在兩個採集的rtt觀測值之間只有微弱的或沒有非線性相關性。
  9. I believe that this development is one reason why the measured distribution of income in hong kong has become more skewed - an increase in the gini coefficient or the area between the lorenz curve and the " diagonal " of even distribution

    我相信這種現象正好解釋為何量度本港收入分佈不均度的堅尼系數較以往增加,即羅倫茲曲線
  10. Stable laws are able to capture the two main characteristics of empirical evidence that returns follow a heavy - tailed and sometimes even skewed distribution

    穩定分佈能夠描述金融數據中的兩個重要經驗特徵:厚尾以及傾斜。
