Based on these graphs: http://img535.imageshack.us/img535/1115/66339819.png What would be a good model that fits the data provided? (i.e. linear, polynomial, trig, or exponential?) And why?|||The first one looks linear. The third one looks sinusoidal with a phase shift. The second one is hard to categorize because of what happens at the far right side. It would be nice to have more data there. I have a hunch that this function peaks, and then declines toward zero asymptotically ... something like a negative exponential. There also are well-known frequency distributions that look like this, but I can't recall which ones (Poisson, etc.)
