What is the difference between GARCH and garchx?
- garchx(eps, order = c(0,0), arch = 1, garch = 1) estimates a GARCH(1,1) since the values of arch and garch override those of order[2] and order[1], respectively. Similarly, garchx(eps,asym = 1)estimates a GARCH(1,1) with asymmetry, and garchx(eps,garch = 0) estimates a GARCH(1,0) model.
What is the garchx package?
- AbstractThegarchxpackage provides a user-friendly, fast, flexible, and robust framework for the estimation and inference of GARCH(p,q,r)-X models, where p is the ARCH order, q is the GARCH order, r is the asymmetry or leverage order, and ’X’ indicates that covariates can be included.
What is an example of a multivariate GARCH?
- Multivariate GARCH Example: Daily returns on Brent crude oil and on gold. Typical result: the series of conditional correlations. conditional correlation 0 200 400 600 800 1000 1200 -0.2 0.0 0.2 0.4 0.6
