Question:
Suppose that the price of gold at close of trading yesterday was $300 and its volatility was estimated as 1.3% per day. The price of gold at the close of trading today is $298. Suppose further that the price of silver at the close of trading yesterday was $8, its volatility was estimated as 1.5% per day, and its correlation with gold was estimated as 0.8.
The price of silver at the close of trading today is unchanged at $8. Update the volatility of gold and silver and the correlation between gold and silver using
(a) the EWMA model with =0.94, and
(b) the GARCH(1,1) model with
= 0.000002, = 0.04, and = 0.94.
In practice, is the parameter likely to be the same for gold and silver?

I am a retired teacher with 6 years of experience teaching various science subjects to high school students and undergraduate students. This background enables me to be able to help tutor students who are struggling with the science of business component of their education. Teaching difficult subjects has definitely taught me patience. There is no greater joy for me than to patiently guide a student to the correct answer. When a student has that "aha!" moment, all my efforts are worth it.
The Common Core standards are a useful yardstick for measuring how well students are doing. My students consistently met or exceeded the Common Core standards for science. I believe in working with each student's individual learning styles to help them understand the material. If students were struggling with a concept, I would figure out a different way to teach or apply that concept. I was voted Teacher of the Year six times in my career. I also won an award for Innovative Teaching Style at the 2011 National Teaching Conference.
