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....
