It would be helpful to know more about the problem.  Like:
- are the points evenly spaced along the independent axis?
- are they assumed to be samples from a continuous signal?
- does the signal have any known structure at all? If you could  
describe where these data come from it might help nail down what  
methods would be appropriate.
