Thank you for this. Everywhere I see an example for AR(1) is shown and AR(p) is simply stated and left.

Very very good video, can you please make play lists and number the topics in an order, you are very good teacher and I think you channel can be very good if you just order it a little bit. Good luck.

This is a very good explanation and presentation. I have a question regarding diagnostics: What types of diagnostics should we use for the model? Should we check the standard diagnostics for the each univariate GARCH model(autocorrelation, (conditional)heteroskedasticity, model stability, residual distribution fit) and also what kinds of diagnostics for the MGARCH estimation? Thank you!

Instead of "setting" epsilon_0 to 0, can you think of 0 as being the maximimum likelihood estimate of epsilon_0?
@user-fo4yh2qj8f
@user-fo4yh2qj8f Год назад
The epsilons cannot be computed without alpha. Where does alpha come from??
@BenOgorek
@BenOgorek Год назад
alpha is a parameter you're trying to estimate. Numerical algorithms will take a starting value, like alpha = .5, compute the likelihood, and travel in a direction towards greater likelihood values.

Hello sir, do you know about how to do mle in markov switching autoregressive?
@rasmuspedersen3195
@rasmuspedersen3195 Год назад
It is considered in Hamilton's 1994 textbook "Time Series Analysis". It is implemented in PcGive for OxMetrics, and I bet that there exist packages for R, Python, etc. as well.

Is the estimator biased? How?
@rasmuspedersen3195
@rasmuspedersen3195 Год назад
For a given number of observations, the expectation/mean of the estimator does not equal the true (population) value of \phi (in general). The estimator is asymptotically unbiased, that is, consistent (under suitable conditions).

thank you so much for the vedio. By the way, what is the correlation here actually describing? the corr between return? or the corr between volatility>
@rasmuspedersen3195
@rasmuspedersen3195 Год назад
It is the conditional correlation between the returns. The model states that this conditional correlation is constant over time.

The same derivations apply to AR(p) models. See for instance Hamilton's 1994 textbook "Time Series Analysis"

How I can use the gmm instead of mle to estimate garch
@rasmuspedersen3195
@rasmuspedersen3195 4 года назад
Indeed you can estimate the GARCH model parameters by GMM instead of MLE. The idea is simply to state relevant moment conditions. See e.g. swopec.hhs.se/hastef/papers/hastef0434.pdf
