I am working with R-1.2.1, package Time Series, under Linux. Please, is it possible to require a Garch only at some specific lags, such as lags 9,10, 17 and 5? (1) If it is possible, how do I specify the lags? The documentation does not says how. (2) It is impossible. I must change the code. Then, I should use another package, such as MatLab or Rats. Which (1) or (2) is true? Thank you, CJoseBento UniNova Lisboa Portugal -.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.- r-help mailing list -- Read http://www.ci.tuwien.ac.at/~hornik/R/R-FAQ.html Send "info", "help", or "[un]subscribe" (in the "body", not the subject !)
