rank difference
1.This paper puts forward a kind of fast and effective method of muting value based on the curvature formula, and it can automatically discern mutating data using half two rank difference method and get rid of the false data.
2.In many cases,people used to equal rank correlation coefficient to Spearman rank correlation coefficient,but the latter one is only the special case of the former.The paper compares the two kinds of rank correlation coefficient through an example,and proves the existence of difference in theory.
3.I am afraid that China will still rank below 50th place among the more than 100 countries in the world, but there will be a difference in its strength.
4.Significant difference was found in vision between the pre-TTT and post-TTT with rank sum M-W test (P<0. 05).
5.Based on isothermal adsorption experiments under equilibrium moistures and high pressures on 20 low rank coal samples whose reflectance’s of vitrifies are less than 0.65%, the relationships of Langmuir volumes, Langmuir pressures between equilibrium moistures, coal ranks, macerals, special hole volumes and special surface areas are respectively discussed. The difference of isothermal adsorption characteristics between the low rank coal and the middle, high rank coal is revealed, and adsorption mechanism of the low coal rank is discussed.
6.Results No significant difference of the median free of bleeding time(MFBD) wag seen between the two groups( 3 1 0 ±58 vs 180 ±44 days, Log Rank test, P=0.087).
7.The study is imitating subulate tool penterite Armor Fabric by Method of Test for Puncture of Paperboard and Corrugated Fiberboard, and to ascertain the laver of Armor Fabric for absorb energy and arrestment, and any difference angle to compare the rank of defying ball, for understanding the sharp to the rank of Annor Fabric defy penterite energy, and penterite deep, the lose energy relation of sharp.
8.RESULTS:The difference of the survival rate s of those whose coag ulated tissue patholog ically positive and neg ative was insig nificant (Log Rank =0.70,P=0.4033),and the differences of the recurren t rates of the primary site,secondary site and the uncertain sit e of them were also insig nificant (χ 2 =1.65,0.837,0.003;P=0.684,0.36,0.959).
