Regression analysis is one of the most common econometric tools employed in the area of investment management. The univariate linear regression model attempts to explain the variability ...
In the next few sections we will use PyMC to formulate and utilise a Bayesian linear regression model. Bayesian Linear Regression with PyMC In this section we are going to carry out a time-honoured approach to statistical examples, namely to simulate some data with properties that we know, ...
17.贝叶斯线性回归(Bayesian Linear Regression) 本文顺序 一、回忆线性回归 线性回归用最小二乘法,转换为极大似然估计求解参数W,但这很容易导致过拟合,由此引入了带正则化的最小二乘法(可证明等价于最大后验概率) 二、什么是贝叶斯回归? 基于上面的讨论,这里就可以引出本文的核心内容:贝叶斯线性回归。
