该研究推导了RNA二级结构中发夹结构和碱基对数量的统计特性,并证明了其分布趋于双变量正态分布。
摘要:
我们推导了RNA二级结构中发夹结构和碱基对数量的期望、方差、协方差以及许多其他混合矩的精确渐近表达式,并提供了充分证据表明,随机变量(发夹结构,碱基对)对的中心缩放分布趋于双变量正态分布,相关系数为√(5√5 -11)/2=0.2123322205…
英文摘要:
We derive precise asymptotic expressions for the expectations, variances, covariance, and quite a few further mixed moments for the number of hairpins and the number of basepairs in RNA secondary structures, and give convincing evidence that the central-scaled distribution of the pair of random variables (hairpins, basepairs) tends in distribution to the bi-variate normal distribution with correlation $\sqrt{5 \sqrt{5} -11}/2= 0.2123322205\dots$
