R语言内置函数(Built-in Functions) R中几乎所有的事情都是通过函数完成的。 R语言中常用的概率分布相关的函数如下: 可以使用set.seed(1234)或其他整数来创建可复制的伪随机数,这样可以保证每次程序生成的概率分布或者随机数是一致的。 在R语言中、概率函数的语法形式为:[dpqr]distribution_abbreviation() 其中方框号...

贝塔分布(Beta Distribution) 是一个作为伯努利分布和二项式分布的共轭先验分布的密度函数,在机器学习和数理统计学中有重要应用。在概率论中,贝塔分布,也称Β分布,是指一组定义在(0,1) 区间的连续概率分布。 1. 生成Β分布的随机数rbeta函数 num <- 1000 alpha <- 2 belta <- 3 x <- seq(0,1,0.01) #...
它以直观的方式描绘概率的分布可能性,尤其是在面对不确定性时,为我们提供了宝贵的分析方法。深入了解并掌握beta分布,将有助于我们在实际问题中做出更准确的决策。参考资料:Understanding the beta distribution in baseball statisticsBayesian Estimation with Beta and Binomial Distributions ...
