事先概率

Prior probability

在贝叶斯统计推断中,先前的概率分布(通常简称为前一个)不确定数量p是在考虑一些证据之前表示一个关于p的不确定性的概率分布。 例如,p可能是将来选举中投票给特定政治家的选民的比例。 这意味着将不确定性归因于不确定数量的随机性。 未知数量可以是参数或潜在变量。 一个应用贝叶斯定理,将先验乘以似然函数然后归一化,得到后验概率分布,这是给定数据的不确定量的条件分布。 以前的经验往往是对经验丰富的专家的纯粹主观评估。 有些人可以选择共轭,当它们可以时,使后验分布的计算更容易。 先前分布的参数称为超参数,以将它们与基础数据模型的参数区分开来。 In Bayesian statistical inference, a prior probability distribution, often called simply the prior, of an uncertain quantity p is the probability distribution that would express one's uncertainty about p before some evidence is taken into account. For example, p could be the proportion of voters who will vote for a particular politician in a future election. It is meant to attribute uncertainty rather than randomness to the uncertain quantity. The unknown quantity may be a parameter or latent variable. One applies Bayes' theorem, multiplying the prior by the likelihood function and then normalizing, to get the posterior probability distribution, which is the conditional distribution of the uncertain quantity given the data. A prior is often the purely subjective assessment of an experienced expert. Some will choose a conjugate prior when they can, to make calculation of the posterior distribution easier. Parameters of prior distributions are called hyperparameters, to distinguish them from parameters of the model of the underlying data.
