Learning outcomes
The goal of this course is to introduce students to the basic tools of Bayesian analysis, and to apply them to make inference in the linear regression model. By the end of the course students will: 1) be familiar with the main steps of Bayesian inference; 2) be able to elicit an appropriate prior distribution; 3) be able to build a posterior simulator; 4) be able to estimate classical and general linear regression models using Bayesian techniques.
Course contents
1. Introduction: Review of the classical linear regression model. Maximum likelihood estimation. The Bayesian approach to the classical linear regression model. Bayes formula. The likelihood principle.The James-Stein result.
2 Bayesian estimation of the CLRM: Theil mixed estimator. Prior selection via the marginal data density. The independent Normal-Inverse Gamma prior. Treatment of the error variance. Gibbs sampling. Convergence and mixing. The Natural .Conjugate prior. Marginal data density. The Normal-diffuse and Jeffreys priors.
3 The Generalized Linear Regression Model: Autocorrelation and Heteroskedasticity. Stochastic volatility models. Metropolis Hastings algorithms.
4 Linear and Gaussian state space models: Kalman Filter. Carter-Kohn algorithm. Models with time varying coefficients.
5 Non-linear non-Gaussian state space models. Sequential Monte Carlo methods.
