A Bayes factor (BF) is a statistical index that quantifies the evidence for a hypothesis, compared to an alternative hypothesis (for introductions to Bayes factors, see here, here or here). Although the BF is a continuous measure of evidence, humans…

From: https://alexanderetz.com/2015/08/09/understanding-bayes-visualization-of-bf/ Nearly被贝叶斯因子搞死,找篇神文舔. In the first post of the Understanding Bayes series I said: The likelihood is the workhorse of Bayesian inference. In order to understand Bayesia…

 bayes因子为什么一定要除以先验机会比,如果是想用样本的作用,来判断支持原来的假设θ_0,H_0的力度,直接用后验概率比不就好了吗?   左边等于右边…

From: https://alexanderetz.com/2015/04/15/understanding-bayes-a-look-at-the-likelihood/ Reading note. Much of the discussion in psychology surrounding Bayesian inference focuses on priors. Should we embrace priors, or should we be skeptical? When are…

pyvcf 中带的一个工具 比其他工具用着好些 其他filter我很信不过~~  自己写的功能又很有限 所以转投vcf_filter.py啦 Filtering a VCF file based on some properties of interest is a common enough operation that PyVCF offers an extensible script. vcf_filter.pydoes the work of reading input, updatin…

[1] ML Introduction a. supervised learning & unsupervised learning 监督学习:从给定的训练数据集中学习出一个函数(模型参数),当新的数据到来时,可以根据这个函数预测结果.监督学习的训练集要求包括输入输出,也可以说是特征和目标.训练集中的目标是由人标注的.常用于:训练神经网络.决策树.回归分析.统计分类 无监督学习:输入数据没有被标记,也没有确定的结果.样本数据类别未知,需要根据样本间的相似性对样本集进行分类,试图使类内差距最小化,…

Example: Polynomial Curve Fitting The goal of regression is to predict the value of one or more continuous target variables t given the value of a D-dimensional vector x of input variables. 什么是线性回归?线性回归的目标就是要根据特征空间是D维的输入x,预测一个或多个连续的目标值变量,大多数情况下我们研究的目…
