Hi Eviews,
I am using Eviews 7. Our University thoroughly enjoys your outstanding customer support and excellent product. I have a question that somewhat pertains to Eviews, and forgive me if it a naive question, but I would really appreciate any insight or suggestions. I am doing a paper to bring awareness to the violence in a certain country, where I am measuring the economic and financial impact of certain types of crime on an emerging stock market. I am getting ready to run a GARCH (1, 1) and I found out that one of my key variables, the crime rate, is only available in monthly format not daily like the rest of my data including daily returns on stock market index, and controls such as S&P 500, exchange rate, etc. If I were to convert my data into monthly format, would the volatility that shows up in daily data still be represented at least to some degree? If you could you please give me any insight into the difference between using different frequencies of data for GARCH (1,1) and its effects, i.e. the market returns are very volatile between 2006 to 2010 on a daily basis, will this show up on a monthly basis as well?
Thanks so much and have a great day. Guero303030 :)

the results may differ.....but i guess u do not have much of a choice here. it all depends on how many months u dealing with.....if it is a long period of time then the difference might be in the value......not the significance if u model the data right of course..... but i did not get why u need to use GARCH?
u mentioned that there is a lot of volatility from 2006 to 2010 i guess u need to check for structural break in that period coz of the crisis.
all the best

Thanks for your insight and taking time to reply. I finally figured it out and your right not much of a choice. I am going monthly; lots of months. All the best to you. Guero303030 :)
