Hi R masters, In my work I analyse a time serie of number of birth in State of Rio de Janeiro. After study de ACF e p ACF I conclude the model is:
Non seasonal ar(1) In 7 days lag 7 days seasonal ma(1) In 364 days lag 364 days seasonal ma(1) If the time serie was Non seasonal ar(1) with one seasonal ma(1) is simple using command arima for fit a time serie, but I don't know HOW TO fit a arima model in a time serie with 2 diferent seasonal periods I attach de file ts.csv with the serie. Thanks in advance.... Bernardo Rangel Tura, M.D, M.P.H, PhD National Institute of Cardiology Rio de Janeiro - Brazil
