在概率论和统计学中,二项分布(英语:Binomial distribution)是n个独立的是/非试验中成功的次数的离散概率分布,其中每次试验的成功概率为p。这样的单次成功/失败试验又称为伯努利试验。实际上,当n=1时,二项分布就是伯努利分布。二项分布是显著性差异的二项试验的基础。 概率质量函数 次试验中正好得到k次成功

之所以称其为 negative binomial distribution(负二项式分布),在于: (r+k−1k)=(r+k−1)!k!(r−1)!===(r+k−1)(r+k−2)…(r)k!(−1)k(−r)(−r−1)…(−r−k+1)k!(−1)k(−rk) 此时不妨对其能否构成概率分布进行简单验证: ∑kPr(X=k)===(1−p)r∑k(−...
distribution (ITU-R2019). The reason why ordinal responses are converted to an interval scale is that proper latent variable models, like ordered logit or ordered probit [see McCullagh and Nelder (1989)], are too complicated for studies with relatively few responses per hidden variable. The par...
Genomic information can be used to predict not only continuous but also categorical (e.g. binomial) traits. Several traits of interest in human medicine and agriculture present a discrete distribution of phenotypes (e.g. disease status). Root vigor in su
