I forgot to explicitly say in the video: the v(i) shown in the MLE equation is identical to the GARCH variance; i.e., v(i) = σ^2(i). The u^2(i) should be familiar as the daily return-squared (which, as mentioned, I suggest thinking of as simply a one-day variance). Also, Analytics Vidhya just happen to post a good on MLE (albeit this is not GARCH specific): trtl.bz/2Lctz19 ... if you find a great MLE tutorial article, please do share!

Curious how you calculate the variance in cell E9 = D8*D8 Why don't you use E9 = VAR.P(D8, D9) ??

Hi Sir how u determine de Raw values for the Omega, Beta and Alpha? Is there a calibration or its just a theoric number?

Please mention all constraints to be used in solver clearly.

That’s too easy of a question…using excel simply set the objective to “Max” subject to 3 constraints… 1) the yellow cells should be able to change 2) the weights equal 1 3) the weights should all be positive values

I used to solver on my data set. Is it normal to get an omega of exactly 0? Would that matter in estimating volatility?

I see that this example deals with just one asset, the s&p 500 index. What if I am observing a portfolio of 3 or more risky assets, how do I go about setting up the MLE model?

Alpha +Beta should be less than one, in your example it was greater than one

it helps to listen to the video (yellow are rescaled "user friendly" values): beta 0.910121 + alpha 0.083390 < 1.0
