hi everybody
when i use mtos it extract columns as a series, how can extract series from matrix by rows?
how to put NA obs in the first and last and in the middle of series, i have 200 obs ( put NA obs between the obs 50 and 51).
i generate arfima by this code (this methodologie is true or not), and can i generate arfima by fix d ( several value of d).

Code: Select all
