# Bayesian_TVPVAR
Bayesian Estimation of a TVP-VAR Model
This repo contains information on how to conduct Bayesian analysis using a TVP-VAR model. Before diving into the code, you should look is the Bayes_TVPVAR_Presentation file. This will give you a baseline understanding of How the TVP-VAR differs from the normal VAR model and how we can cunduct Bayesian analysis in the TVP-VAR setting. Once you have a decent grasp on this, the code should be a little easier to follow.
Before moving on to the code, I want to cite the authors that the code was obtained from. The main source was from "Bayesian Multivariate Time Series Methods for Empirical Macroeconomics" (Koop and Korobilis, 2010) and only slight modifications were made to this. This was the main textbook that most of the information for this project was obatined from. There are many different files and functions contained in the file TVP_VAR_CK, so to avoid being overwhelmed by the MATLAB code, restrict your focus to three main files. One, the Homo_TVP_VAR.m file is set up to read in data from Korobilis (2008) and reproduce the impulse response functions from his paper. This will also do the bulk of our homoskedastic TVP-VAR Bayesian analysis, which is the section that we will focus on. Lines 260-263 is where the posteriors of our parameters show up in this file. Two, the ts_prior.m function (where the ts stands for training sample, not time-series) sets the priors on our variables for our training sample. Three and finally, the carter_kohn_hom.m function runs the Kalman filter forwards so we can obtain the draws for our parameters via backwards recurssion.

温馨提示
贝叶斯_TVPVAR TVP-VAR模型的贝叶斯估计 此仓库包含有关如何使用TVP-VAR模型进行贝叶斯分析的信息。 在深入研究代码之前,您应该看一下Bayes_TVPVAR_Presentation文件。 这将使您对TVP-VAR与常规VAR模型有何不同以及我们如何在TVP-VAR设置中进行贝叶斯分析的基线了解。 一旦对此有了一个不错的了解,代码就应该更容易理解。 在继续编写代码之前,我想引用从中获得代码的作者。 主要来源来自“经验宏观经济学的贝叶斯多元时间序列方法”(Koop和Korobilis,2010年),对此仅作了一些修改。 这是该项目的大多数信息都被引用的主要教科书。 TVP_VAR_CK文件包含许多不同的文件和功能,因此,为避免被MATLAB代码淹没,请将您的注意力集中在三个主要文件上。 一种是设置Homo_TVP_VAR.m文件,以从Korobilis(2008)读取数
