[R] A question on seasonal time series - R package
Hi there, I am using the "ts" class of the "R" package. I have a data file containing a time series of 1152 entries. It is actually 4 days data cascaded together where the time interval of data collected is 5 minutes. Thus, I have 288 values per day. When I am trying to fit this data using a period of 288 with a seasonal model, using the arima(...) function, I am getting error message "Error: makeARIMA(...): negative length vectors are not allowed". I am not sure what is the problem. I really appreciate some help on this.
