The parameters of a GARCH(1,1) model are estimated as = 0.000004, = 0.05, and = 0.92. What is the long-run average volatility and what is the equation describing the way that the variance rate reverts to its long-run average? If the current volatility is 20% per year, what is the expected volatility in 20 days?

Suppose that GARCH(1,1) parameters have been estimated as = 0.000003, = 0.04, and = 0.94. The current daily volatility is estimated to be 1%. Estimate the daily volatility in 30 days.
