贝塔分布概述 贝塔分布（Beta Distribution）是一种连续概率分布，通常用于描述随机变量在0到1区间内的概率分布。它由两个正的形状参数α（alpha）和β（beta）定义，这两个参数共同决定了分布的形状。贝塔分布广泛应用于统计学、机器学习、项目管理和风险评估等领域。核心概念与特性 1. 定义： 贝塔分布的概率密度...

最近在学习一些关于alpha beta sample size的问题。看到一些有意思的链接和内容。 比较清晰的解释了alpha, beta的关系,还用R code的实例。 这是一篇某大学的材料,讲解sample size and power 关于Binomial distribution Probability mass function Cumulative distribution function 一个很清晰的二项分布的介绍。 There're ...
This report shows that a difference between the citrate-soluble collagen molecules of 'normal' as compared with those of chronically ill patients is in the relative distribution of their component polypeptide chains, that is, the alpha and beta components. 展开 ...
DistributionAlpha-Beta-GammaSkewNormalDistributionFisherInformationIn this paper, a new class of skew multimodal distributions with more flexible than alpha skew normal distribution and alpha-beta skew normal distribution is proposed, which makes some important distributions become its special cases. The ...

(these analyses include all choices, not just correct ones, Fig.1d). When there was a reward in the previous trial, the likelihood of choosing the same response (meaning long vs. short) was significantly larger (paired-samplettest,t = 5.9,p < 10−4), supporting the idea that...
