Modelling heteroscedasticity in Stan: Should I invest in the Stock Market?

Welcome to the official Stan youtube channel! Stan is a state-of-the-art probabilistic programming language. Here we will be releasing new videos regularly covering everything from how to use Stan to bayesian statistics. This video is an introduction to heterogeneity. I will discuss the difference between homogeneity and heterogeneity, the importance of understanding and incorporating heteroscedasticity in your models and finally how to model heteroscedasticity with ARCH and GARCH models using the FTSE stock price as an example.
