Hello I m a student in PARIS X university (France).I m preparing a working paper dealing with the presence of long memory in finantial markets. I have programs computing the hurst exponent by the rescaled range method and the GPH method (Geweke Porter-Hudak). I want to apply the modified rescaled range method proposed by A.Lo (1991). AS i m beggining with RATS i couldn't do the progam . can you send me the program (for RATS ) computing the hurst exponent with the modified rescaled range method or tell me where can i find them. please help me i can't find it anywhere. thank you ___________________________________________________________ Do You Yahoo!?
