I am trying to asses which type of time series will best fit my daily unique visitors' forecast; I used TS Plot to compare Time series and time series decomposition plots; Time series plot works just fine; but I get an error with time series decomposition plot - Error: TS Plot (17): TS Plot: Error in plot(stl(the.y, s.window = freq)); Any thoughts on how this could be fixed? my dataset has date variable and daily unique visitors variable.
The decomposition plot requires more than two full periods of data (for example if your data is weekly, you will need > 104 data points). I suspect that your input data does not satisfy this condition, which is probably why you are getting an error when you select the decomposition plot. If you can share your data, I can take a closer look.
