homogeneity assumption 中文意思是什麼

homogeneity assumption 解釋
同質假設
  • homogeneity : n. 1. 同種；同質；同性。2. 【數學】齊性，均勻；同一性，均衡性，均勻性。
  • assumption : n. 1. 採取，承擔。2. 假設，假定；臆說；想當然。3. 傲慢，僭越。4. 假裝。5. 〈A-〉聖母升天（節）〈8月15日〉。6. 【邏輯學】小前提。
  1. Knowledge of the violation of the homogeneity assumption would allow the investigators to choose sophisticated methods of phylogenetic reconstruction ( lockhart et al. 1994 ; galtier and gouy 1998 ; kumar and gadagkar 2001 ) or to conduct phylogenetic analyses with the offending sequences removed, if possible ( nei and kumar 2000 )

    並且基於對違反同質性假設的認知，研究者可以選擇一些關于系統發生重建的高級方法（ lockhartetal . 1994 ; galtierandgouy1998 ） ，或者如果可能的話，將那些冒犯這個假設的序列去除之後再來做系統發生分析（ neiandkumar2000 ） 。
  2. Although violation of homogeneity assumption is known to adversely impact the accuracy of phylogenetic inference and tests of evolutionary hypotheses, testing such the assumption has been little investigated to date

    盡管違背了這個假設就相對地影響了系統發生的推論和進化假設測驗的粘度，但檢測這個假設卻鮮見研究。
  3. Furthermore, analyses of dna sequence datasets with the violation of the homogeneity assumption is not only useful to elucidate the evolutionary mechanisms that have shaped the observed differences in genes and species with atypical substitution process, but also provides important clue for the future development of phylogenetic methods

    更進一步地，對于違反同質性假設的dna序列數據集的分析，不僅用於闡明在非典型替代過程下的基因和物種形成的可觀察到的差異的進化機制，也為深入研究系統發生的方法提供了重要的線索。
  4. Recently, kumar and gadagkar ( 2001 ) proposed a simple measure, disparity index ( id ), to quantify the difference in observed substitution patterns between molecular sequences, and use it to develop a statistical test as the probability distribution of this statistic ( id ) is unknown, monte carlo approach must be used to test the null assumption of homogeneity

    近來， kumarandgadgh （ 200 ）提出了一個簡單的測量一差異指針（ isparityindex ， id ）來量化這種在分子序列間觀察到的替代模型的不同，並用它發展了一個統計檢測。由於這個統計量峋）的概率分佈是未知的，故必須利用montecarlo方法來檢測這無效同質性假設。
