Hello forum members, I am taking this R course which I have to admit that it is beyond my capability. I am asked to analyze the following data(file attached) according to the question provided below:
1. The file [data_13-9.txt] contains a data of length 225, which seems to have some cycle pattern. (1) Fit a suitable model for this data, then report the model equation. (2) Provide the forecast values for 3-steps ahead and 6-steps ahead. I am desperately seeking for your help, since I really don't know where to start.. I have done "plot.ts(data.13-6)", but not further. Above question is just part of the whole task, but I believe solving this would be very much helpful for me to jump in to the other questions. It would be easier for me to follow if your answer is in R script.. I appreciate your patience and help. Thank you so much in advance! Cheers, Lia
