Hi everybody, I am sorry that I am kind of spamming this forum, but I have searched for some input everywhere and cant really find a nice solution for my problem. Data looks like: price 2011-11-01 08:00:00 0.000000000 2011-11-01 08:00:00 0.000000000 2011-11-01 08:02:00 0.000000000 2011-11-01 08:03:00 -0.017033339 2011-11-01 08:13:00 0.000690001 2011-11-01

Hi, we have a problem concerning the use and forecasting on the GARCH (1, 1) on financial data. We would like to make predictions on future returns in a loop which moves the window of estimation forward one unit for each iteration. Our code is as follows: > BJORN <- read.table("C:/Users/Osvald/Desktop/DATATILLUPPSATS.txt", + header=TRUE, sep="\t",

Btw, in the earlier mail i forgot to mention what the error message was. The R console tells us that: "Error in matrix(0, ncoef, ncoef) : invalid 'nrow' value (too large or NA)" before it has done any estimations. i couldnt attach the data in the mail, so i write it manually in text.
