Hi guys, i have three standardized residuals series derived from ar(1,1)-aparch(1,1). after that i used ecdf function to each of the three series. now i want to proceed with copula fitting using copula package. can anyone point me in the right direction as to the r code and goodness of fitness test. also can coupla fitting be done ecdf derived above or i have to use a uniform distribution but i guess thats what ecdf does, please confirm.. thanks, mudit [[alternative HTML version deleted]]
