Too expensive? It depends. I put this item here is not for the pursose of making money. Most of us using the G@rch package of OX to estimate FIGARCH model, but the problem is the most of the time it does not convenge. Another reason is that it is not easy to expand or incorporate other variables in the model estimating especially when we got some new idea. I put this procedure who is orginally done bythe GURU of this model is to motivate my dear fellows friend who are active in research and and writting to explore more in the future.
I do hope that with this basic procedure my dear fellow friends will a lot new things to be done.
Work hard but work Smart!!!
