Very good explanation Dr. My question is I was trying to fit time series for WIPRO stock prices but P values for mu and omega were not below 0.05, hence rendering them statistically insignificant in the sGarch model. What could I do in order to get those values below 0.05

Thanks a lot for the video. It's very helpful. How did you call up this information board about optimal parameters? If I run m always appears a plot selection.

Dear Mr. Bharatendra Rai, Do you maybe have a similar approach for multivariate garch. I am looking at DCC-Garch rolling forecast. However the package "rmgarch" in R does not have a "report" function like "rugarch" and does not report the backtesting results of Value-at-Risk. As backtesting is the only way to validate and see if the model is any good (by looking at how many times the model forecast exceeded 5%), it is very important to have this result. As I said, it is given in univariate package but not multivariate one. Any help is greatly appreciated. KR.

Hello sir, I have one question related to adjusted pearson goodness of fit test. In goodness of fit test we can see output results we got three columns one is "groups" second is "Statistics" and 3rd is p-values. But I didn't understand what is column of groups what is groups 20,30,40 and 50.

Mr. Bharatendra Rai, aren´t the arch lm tests being inconsistent with the garch regression?

I have a question, can the garch model be used to compare the volatility of 2 stocks ? for example apple and microsoft and if so on what basis are we comparing ?

my model for mean is ARIMA(p=4,d=1,q=2,seasonal=order(P=2,D=1,Q=2),period=7); then when i'm going to write this model in the function ugarchspec(), then in armaOrder i only can define p,q values but can't define d,P,D,Q values. How to do that??
