st: predicting billion songs countdown
Has anyone attempted to use Stata to predict Apple's billion songs countdown? They have a counter going online at their site. The billionth song buyer gets a prize.
I don't know if the online pace reflects real point of sales timing and I also suspect that its current pace would accelerate closer to the target (I did not find any prior curves or information on their prior contests). I thought this would be an interest teaching exercise.
What Stata commands would be used for this kind of prediction? I've not done time series analysis, but was curious.
