Each piece of data represents a small time period and change in value.  Think of it as something like a stock ticker, very noisy with a larger trend upward. From the patterns in this random data we can visualize it and try to predict what that phenomenon might do in the future. We will get a range of realistic futures and a sense of what the average looks like.\r\n<p>\r\n\r\nPolynomial fitting is problematic, so instead bootstraping of data will be tried.
