I use R to estimate a Multivariate GARCH(1,1) model for 4 time series. I tried it with the rmgarch package. Seems like I'm using it wrong but I don't know what my mistake is. First time using. lib...

Given the specified component models, you would supply them to the relevant function in the "rmgarch" package to build the multivariate GARCH model of your choice (DCC, GOGARCH or copula GARCH).

Tutorial Overview

Is there a package to run simplified multivariate GARCH models in Python? I found the Arch package but that seems to work on only univariate models. I'd like to test out some of the more simple methods described in Bauwends et. al. (2006) like constant conditional correlation. Python libraries are preferred though I'll play with R as well.

Financial Risk Forecasting is a complete introduction to practical quantitative risk management, with a focus on market risk. Derived from the authors teaching notes and years spent training practitioners in risk management techniques, it brings together the three key disciplines of finance, statistics and modeling (programming), to provide a thorough grounding in risk management techniques.

Below is the formulation of a GARCH model: y t ∼ N ( μ, σ t 2) σ t 2 = ω + α ϵ t 2 + β σ t − 1 2 We need to impose constraints on this model to ensure the volatility is over 1, in particular ω, α, β > 0. If we want to ensure stationarity, we also need to ensure α + β < 1.
