The Beta Distribution beta分布与伯努利分布不同的地方在于,伯努利可以描绘discreate value,beta分布描述的是连续性的取值区间(所以我们可以Model上图这种理论上interval可以无限小的数据。 接下来看看Beta分布的probability density function (PDF), Beta(p;\alpha,\beta)=\frac{p^{a-1}\times (1-p)^{\beta-1}...
所谓的以\alpha, \beta为参数的 Beta 分布f(x; \alpha, \beta)，其实描述的就是我们在做抛硬币实...
beta binomial distribution
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 ...
Skew distributionAlpha–beta-skew distributionBimodal distributionAICRecently there is a lot of research related to skewed distributions and their growing relevance in data analytics. In the present work we introduce a new generalized version of alpha beta skew normal distribution and some of its basic...
🐛 Describe the bug There seems to be a numerical problem when sampling from torch.distributions.Beta with $\alpha=\beta\to 0$: import torch import matplotlib.pyplot as plt x = 1/1000 pdf = torch.distributions.Beta(torch.tensor([x]), torc...
